2G Need help figuring out whats wrong.

[Kdouglas89]

To make things short, I took my head off basically I thought i bent a valve. Realized I didn't. I went ahead and upgraded valve springs, seals, and put a cosmetic head gasket on.

The car runs like crap. Hardly any power. It idles fine in park, but once I put it in gear, the idle drops down to about 300, and if I am driving, once I release the gas it wants to die, idling at around 150-200.

I am in time, I did a boost leak test and I am holding air fine. I have not done a compression test yet.

I am having issues with a battery draw somewhere, and Ive had this issue before I tore head off. Its a brand new battery with a new alternator. Car was running and charging fine before I tore head off.

99 gsx w/ 95 ecu. I have link V3 if I could use that to help.

Any codes, post a log

 

[Kdouglas89]

No codes, Won't be able to post a log until tomorrow. Car is dead in the garage. Jumped it just to get it there.

 

[Kdouglas89]

This is an idle log from a few days ago.

Do a compression test.

 

[dominick8000]

id do a compression test

 

[gofast63]

Do you have a afr gauge?

 

[gofast63]

I seen it on your profile. what does it read when its idling really low

I seen it on your profile. what does it read when its idling really low

I have one, but I am in the process of re-wiring it. I either have an exhaust leak, or its wired weird. It runs 20's when idle, and it jumps around between 14-17 while driving.

 

[gofast63]

you must have an air leak somewhere or your o2 sensors arent getting a proper reading from an exhaust leak. you can buy gasket material at the auto parts store and cut out the gaskets you need for cheap. Less of a dent on the wallet. Plus i hate waiting for $*** to come in the mail.

Check mechanical timing. Are you sure you did it correctly?

 

[Kdouglas89]

Yes, my gears, crank, oil, and BS are in time.

 

[gofast63]

Start your engine and plug your muffler with a rag and have someone listen for any sising noises.

 

[Kdouglas89]

I am not leaking out of exhaust manifold, Double checked and I am in time, and compression is roughly 170 across the board. Blahhh, any other help?

 

[Kdouglas89]

Someone? Pretty much stuck here.

 

[gofast63]

Check you tps sensor

 

[Kdouglas89]

Check you tps sensor

I was actually thinking this last night but it must have slipped my mind. Would the tps cause complete loss of power though? Just Seems when I let off the gas it drops to 150 rpm and runs VERY sluggishly

 

[ohlegend]

Maybe a leak at the intake manifold? Did you use the old gaskets or put new ones on?
Make sure you plugged everything back in too.

 

[gofast63]

what does your tps read on your dsmlink?

 

[Calan]

Why are you pulling so much fuel at low airflow, and why have your open loop thresholds been changed?

 

[Kdouglas89]

ohlegend - New gasket, and from what I see everything is plugged in.

gofast - from my idle log, its .65 at idle, I will check WoT in a minute.

Calan - What do you mean pulling so much fuel? I know I have my deadtime at 555 to keep my combinedFT at as close to 0 as possible. Where are you seeing my open loop thresh holds? That is something I should not have messed with seeing I have no clue what it is!

Thanks for the input guys, and appreciate all the future help.

MAFComp sliders, and DA table

MAFComp sliders, and DA table

MAF was adjusted by dsmlink when I did a cruise log. They were pretty eratic so I smoothed them out a bit. I just compared my open loop thresh holds to a previous log I had, and it is exactly the same. I have not touched that section. I bought link brand new.

 

[Kdouglas89]

what does your tps read on your dsmlink?

Link is reading .63 and 5v at WoT

Besides fixing your voltage issue (which can cause all sorts of problems), go down this checklist:
