Rough Idle, hesitation, no engine codes
I had some trouble codes, engine running rich and the car had bad hesitation (undrivable), which led me to replace the MAF, and the O2 sensors. I have done the PVC valve/gromit, gapped the plugs, Dist cap and rotor. Fuel filter is new too. Checked for vac leaks best I could. No more codes, and the exhaust smells better. Rough idle is still there, and the hesitation while accelerating is still there but VERY subtle/intermittant. Now the RPM gauge is bouncing around a little. Just wondering if my computer might be going bad. When I do a KOEO test with a scanner, I can't do another one right after it, unless I shut the ingition off/back on. I don't remember having to do that before.
...or is it a vacuum leak that I cant find?
