Car starts, but idles rough and vibrates, press to accelerate, sometimes it revs, but when I put it in drive, no power, it goes very slow and vibrates and sounds like its missing.I took compression test, all 160 to 165 psi, all spark plugs firing, all fuel injectors working, I moved the distributor all the way left slowly, and all the way right slowly, I put in new spark plugs and took them back out twice, they were sooty black, clean them still sooty black, what should I try next? This really need some help. My friend says its the PCM (computer).
But I did not take it out. Also car has automatic transmission.
