Misfire/hesitation while cruising now worse!

[szewczyd]

Well it all started about two months ago. I was driving and my car seemed to hesitate or misfire while accelerating. Not bad but very noticeable. Then it turned into sputtering/misfire while just cruising along no matter the speed. Then a few days later it started misfiring terribly and I couldn't accelerate at all and had no boost what so ever so I pulled over. Checked my wires to make sure they were all plugged in and then checked my translator plugs to make sure they all checked out, which everything did. So I close the hood started the car again and it was still running on like three cycliders. Shut it off again waited a while and then tried again and it was fine but still missing all the time while cruising. Drove for about a week and then it did it again running on like three cyclinders, this time I nursed it home and did the same inspection, and then just let it sit. week later still only three cyclinders and now it will not start at all! Any ideas?

P.S Sorry for being so long but it seemed to progress and get worse and worse while I hadn't changed anything nor had I beat on it at ll.

Just so you know it didn't do all this in one day it did this in about a months time, driving it pretty much everyday.

Well I did what you all said I put on new wires, new plugs I did the 3214 order and then cleared the ecu by disconnecting the battery. HIPPI the car started, since it hasn't been run in a month I let it warm up fully and then took it around the block, didn't get on it just drove it. Made it with no problems. Started to head to shool, made it about 5 miles and then it started again, missing really bad and stumbling on itself. So I nurse it home again and I am pretty much back to where I was!

every time i've ever encourted phantom engine problems like this (random and mechanically unexplainable), it's been an electrical probelm and usually related to a bad ecu. it's not hard to pull it out and inspect it for leaky capacitors. i know it's a problem in 1g's, but your car is 10 years old now. it's worth a check. does cel come on when this happens?

 

[szewczyd]

No I get no check engine lights. Its strange because it was just fine and then all of a sudden went all to hell again, which makes me think its not the ecu, but I have had this ecu repaired two times allready. I will have to see if my buddy will let me use his ecu for a day and see if there is any difference.

Hey guys, I'm having a similar problem and it doesn't happen all the time. My problem isn't happening while accelerating but when I'm cruising in 3rd gear around 3000 rpm and it's not chugging but feels like a hesitation just a small miss. Car did sit for a while and this trying to get to all the little problems and this is the last for now. Fixed the ecu when I got the DSMlink version 3 with new capacitors and tuned at Magnus. New plugs and wires but might think it could be coil pack or injectors. I did buy a new fuel filer and just finished a full tank with injector cleaner. I'll up date this thread if the replacement of the fuel filter works. Please let me know if there should be other things I can look at. Thanks for your time because it gives me so much stress to see this amazing looking car out of the garage after 10 years and just want to have some fun driving it.

Ive seen a maf do this. Check wiring and the maf connector. Also the PTU connector can get very squirrely

Running DSMlink v3 and for the last two days tired to change my fuel filter with a universal which we figured out that it doesn't fit. I will get the OEM one Thursday. I'm really not sure maybe injectors might be the problem. Didn't drive the car for ten years just starting up and moving in and out of the garage. I'll check the coil then injectors.

Have your checked if the injectors are firing, maybe dirty and clogged. And I agree on checking the Maf.

Check plugs and wires, had the same issue on my 1g for a while and was so annoying... First plugs went bad and fixed the issue, next the plug wires after I got the plugs in a week or so after... Could be a few other things, coil pack. I was seriously contemplating things such as CAS or maf... Stuff that was more expensive than plugs or plug wires, luckily it was a simple fix, so try that, it's worth a shot.
