Car is a 01 civic Ex. D17a2 with about 90k on the motor.

I'm getting random misfire codes. Usually on cylinder #2, sometimes on 1,3 & 4 if i don't drive it for a few days. It has a jumping idle, but only after I reset the comp. It also has no power (which is a given), And it surges and backfires alot. Its worse during light throttle, and at tip in.

I changed the plugs, swapped coil packs around, cleaned the tb, and ran some sea foam through it. Car still runs like crap, but now there are no codes.

I don't think its the hg, because there is no coolant in the oil.

I'm gonna try to find somewhere to do a fuel pressure test on the low low, cuz i don't have the tools.



Any suggestions?
