So we got my car running a few weeks ago. We got the shell and it was pretty hacked up to say the least. WE fixed everything we saw and built this
2.3 stroker 7bolt
Block
Forged steel crank
Scat rods
Ross 9.0:1 racing pistons
Acl race bearings
ARP Hardware
Head
Evo 9 springs, retainers, rockers, lash adjusters
Evo2 cams and cam gears
Arp head studs
Multilayer head gasket
FMIC
I am running stock ecu, stock injectors, and stock timing. When car was started it ran great, then was having issues with clutch. We fixed that. THen after driving it for like 100 miles it started randomly running like crap. it would misfire and just studder and would not accelerate. smelt like it was dumping fuel. Then it kept getting a little worse and worse. I then realized my home depot 90 degree coupler blew a hole in it when I was on a 35 mile trip. seeming it started to run better, but was slow bc of a huge boost leak but it ran smoother and didnt backfire. I then got yet another home depot 90 degree coupler ( my new ones were on order and needed the car as my daily driver took a shit on me) Instantly it started running bad agian. THe idle was high(2500) and jumpy then went to 300-500 and jumpy could barley keep it alive. I then checked the spark plugs and they are all black as hell and looks to be running rich crazy rich. so I replace the plugs with some NGK's.
Now I start car and it runs decent still a little lumpy idel but was at lke 1200. I took it for a spin and by a block I was running terrible again. I then realized nothing I would do with the gas would make it better other than giving it 80% throttle. then it will hesitate for a second then just fly and run great. till i let off gas a bit.
I changed ecu's and it didn't fix problem. I checked all couplers and got them all tight and everything seemed great. I know there are prob a few small boost leaks but nothing to cause this kind of problem.
A few other possibly non important facts. When my buddy hooked up his tactrix cable to the 98 ecu he has it didnt work saying not enough voltage, but worked fine in his car we checked right after.
my CEL does not come on with three different ecu's that we have tried (assume the light is out or something)
I know this is a lot but I do not know where I should start.
thanks again!
