If I let off the gas it still does it. The speed is random, I've had it happen at 35-40, then while I'm cruising at 55-65. A friend of mine suggested that a rivet could've popped loose on the friction disk

less than 4k

anybody?

While driving to work this morning I had some potential clutch shudder going on. While I'm driving, all of a sudden the car starts shuddering. Vibration coming from the front. Once I push the clutch in it goes away. It comes back randomly. Could this be some clutch plate spring issues?I've got...

The motor mounts are all new prothane mounts. I noticed that if I rev it up higher I don't get as much clatter.

I replaced the TOB, the clutch kit and the flywheel. Yes the pedal is adjusted.

I have some weird issues going on with my transmission. When I pull out in first gear, the clutch is grabbing and causing the car to shudder. This is only happening when I have the clutch pedal coming back out. The car shifts into gear fine. It's when I'm letting off the clutch it's grabbing...

watched this event last night and I was very pissed about the GSP fght. I'm tired of watching this guy go 5 rounds with guys. He hasn't finished a fight in awhile. I believe the super fight with Silva HAS to happen to save GSP's run to "greatness" However I was very happy with every other...

ok well that leaves that thought out.. hmm not sure what else it could be then

just thought I would update this post as I still have issues.the issue is still happening and i've put on about 1000 miles. Doesn't seem to be getting any better. It seems to be happening almost right at the top of the clutch play. It's like a sweet spot, I can even feel it now when i'm down...

like my profile says I have evoscan. I also have the ceddymod flash so I believe I could turn it off that waywould that explain why my wideband is reading lean

No. I've had it plugged in and not in the exhaust before with no issues.

I finally figured it out, after trying and trying I decided to go back into a virtual XP mode on my windows 7 machine and wouldn't you know. I can read the code, after all this time I forgot that I unplugged #2 02 sensor since I have a wideband in. I feel like such a idiot. Now my question is...

I can't pull codes. I can log. I know it doesn't make sense.

I can communicate to it because I can log in evoscan. that connects just fine. but just to make sure, where is that fuse located at? under the hood or by the clutch pedal?

My check engine light comes on but I can't freaking clear the damn thing, I tried reading it on evoscan and it won't connect or I get an arithmetic error. Anyone ever get this error before

I was out trying to reflash my 99 gst spyder back to its stock Rom file and I get half way through and it failed to flash and the fuse box is clicking and hearing a clicking noise in the back of the car, I can't start the car or anything. I tried to reflash the ceddy mod version but it fails...

I finally got my new version over the weekend. Installed it and I STILL get the same error. I try to read the CEL and I get the arithmatic failure. I'm about to give up.

I've logged into the site and they don't have any of my info on file what the crap is that?? It's been 4 weeks now and I haven't heard a peep out of them.

thats what I figured, everytime I go out into my car in the morning I start it up and it goes all the way lean, then slowly works it's way up to 14.7. LETS FORGET ABOUT TURNING UP THE BOOST, and get this problem figured out first. Also I do have evoscan which I like, just waiting for them to...

anyone have any luck getting the newest version? I've sent in 4 'helpdesk' tickets in and haven't heard anything back

i'm at stock boost right now, with my setup what would be a safe boost level?

Just got back from a nice long ride. I did some 3rd and 4rth gear pulls up to redline and it seems to be normal. when I get up past 5k it's in the 11s. I ran it up to redline and noticed it didn't have a reading and all the way to the left so I don't know if thats too rich.

no I didn't make a 6k rpm pull. Tomorrow i'll go for a ride and see what the reading is in a 3rd gear pull to 6k.

I'm running stock boost, with stock injectors and a 190 fuel pump. when I say WOT I mean i'm driving and then I put my foot all the way down.

what would cause it to run lean at WOT?

so the higher numbers mean it's Lean correct? why would I be super lean at idle?

Just put my AEM wideband back in. I put it in the 2nd 02 sensor bung (downpipe, and greddy turbo back exhaust no cat) what should my readings be for a stock setup. when I first start up the car its all the way to the right in the red, it doesn't give me a number. then as the car warms up it...

Yes it's plugged in, I swapped out 2 of them with the same results. I cleaned the connectors and everythingwell it has to be the wiring, I put in one from a friend who's works and I still get the cel. I'll try and disable it with the ceddymod flash

I keep getting the p1104 engine code. It doesn't say a description but from what i've read its the BCS, I went ahead and replaced that it, reset the ECU it comes back after I start the car up the 2nd time. What the heck could be the issue, just to make sure I have the hoses connected right, the...

sure, pm sent with email. thanks

could be, but then you would "think" it would work fine with XP virtual mode. After all thats the whole point of having the virtual xp mode, so programs can work that don't with 7 yet

I'm going to see if another guy can come over with XP and try it out with the same cable. The cable is supposed to work fine with evoscan so I don't think that would bet he issue.

It's weird how it worked fine with Vista 64bit. I even tried it on a Windows XP virtual PC and still fails.

what bit windows 7 do you have? It worked fine for me when I was running Vista 64 bit.

I'm using the Tactrix openport 2.0 cable. the USB cable part busted on mine so I'm using one from my PS3 (used to charge the remote) I don't think that would make a difference though.Tactrix Openport 2.0

Anyone running win 7 and evoscan 2.7 having issues reading CELS? I get 2 error messages when trying to connect to read the codes. keep in mind that I can log just fine. The error I get is either- 1. Cannot read from ECU 2. Arithmetic operation resulted in an overflowanyone ever have this...

rebooted and reinstalled, still get the same problem. This only happens now that I've got win 7. With Vista I could pull the codes fine.

Yeah but isn't running the ceddy mod supposed to get rid of cels. And make the check engine light a knock gauge? I went out and tried to read the Cel light but Evo couldn't read from ecu in my windows 7. It has done this ever since I switched to 7. I installed it on my XP virtual machine and it...

I'm running stock boost. I was throwing a CEL before I flashed it was for the evap solenoid. I got a new one and hooked it up and then flashed. Tomorrow I'll go out and reflash to stock and see what we got for CELS. I am running at 1g CAS advanced to 5 degrees if that would make a difference.

today I went out and flashed the ecu on my 99 gst spyder. I only did this to up the idle during neutral, added 150 to the table. after the flash I have some ? about the knock on cel light. my light stays on almost all the time now, it will go away once in awhile, I;ve seen the needle hit the top...

anyone know the part number for the convertable top ecu (this is the one located behined the backseat backrest part. Its located on the drivers side with 3 plugs going into it. I think mine is going bad my top only works sometimes along with the windows. If I wiggle the wires sometimes the top...

anyone ever heard of this - "Arithmetic operation resulted in an overflow." I'm throwing a cel so I hoooked up my evo scan to it and thats what it says.

I never thought about that, the flywheel causing idle issues. Interesting. I actually just changed my plugs couple weeks ago. I'm running a stock rubber intake pipe with K&N cone filter. Running stock boost on a 14b turbo. 2100 clutch kit with lightened flywheel. (its not the super lightweight...

I adjusted the the TPS yesterday following your steps. I ran seafoam through it last night, I'm in the car right now with my evo scan hooked up and its currently idleing at 781-812it only wants to die down after I rev it up 6k or I bounce the throttle around from around 3-4-5On my evo scan...

I just went out and tested the ISC with the ohm reader and also turning the key on and watching it click and move, both came out fine.So that pretty much removes the ISC from the problem, what could it be now?

2Gs have the EGR on the firewall, and then I have the other part capped offanyone else?

What controls the Idle so when I rev it up at Idle and then let off the pedal it doesn't die. I changed out the TPS, made sure it was good use the how to guide on here and I still get idle drop. I can get it to idle good just sitting but when I rev it up high it will almost die. What causes...

Does the 99 eclipse turbos models have a different type of TPS. Reason I ask is because I found the original tps off my engine that was stolen and it had 4 terminals, the one that was on my 95-96 engine ony has 3.The 2nd reason i'm asking this is because my car will idle good but when I...

awesome the 2nd one is exactly what I need
