Okay, my '91 LX is still running like crap. I have searched the threads here and have tryed everything sugggested in them but no luck. All of my mods had been on the car for a year before the problem started.
For the problem. It started about a year ago when it was becoming difficult to start when cold (cranked a long time before firing), but started fine when hot. It progressivly got worse until it is where it is at now. It will fire right up, but it sputters and stalls on cold start. When it stays running it idles kinda rough, it also backfires out the intake and bucks a little when driving until it is warmed up. When it is warmed up it has no power below 3000 RPM.
Now for what has been done to fix it so far. I pulled codes And have done repairs accordingly. I can't remember the codes but as for the repairs I have replaced the evp, ect, act, tps, idle control assembly, spark plugs, cap, rotor, wires, TFI module, coil, timing chain and added a MSD 6A module. My fuel pressure is at 45 psi, timming is currantly at 20 degrees but has been retarded all the way back to 10, but runs better with more advance, and compression is at 110 psi but I don't trust my gauge I want to check it again with a different gauge.
Sorry to be so long winded but wanted you to have all the info. Any help would be great, Thanks
