1G 1994 Eclipse cutting out.

[abadz28]

I have a 1994 eclipse 1.8 auto. The car after sitting will start up fine and runs great. It will just random start jerking, missing, tach jump or just go to 0. If I just park the car overnight it will run again. Sometimes for 5 minutes before it does it or 30 minutes. If I just play with the throttle and get it reved up it may clear up. Or if at speeds turn overdrive off and get reved up a little I can get it to somewhat clear up. If I make it thru it doing it for about 5 minutes it will straighten up and run again. I have went thru 3 different ecu(one of which came from a running car) and had the same problem. Changed the coolant sensor also. Car is showing no codes. Kind of at a loss. Check ohm's on injectors and all were same. (unless one is breaking down after running). Only other issue with car is that it does have a noisy lifter that will quiet down after running it. Sometimes it goes away and sometimes it doesnt. Dont know if thats relevant but want to give all info I can. I currently have 4 of these cars and have never not been able to fix so I'm kind of stumped.

Thanks

Power transistor (ignitor)? Might explain the misses. No one else chimed in so I figure I'd take a stab. I believe there's a "how-to" on testing them on here too. Good Luck

Your defiently getting a random misfire but maybe not as obvious enough enough to throw a code, check the cables and spark plugs go on the easy stuff first before you go big.

Plugs and wires have been changed. Yesterday I had read a post with similar problems and it was maf. I have a extra one that's off a 2.0 that I tried on it and when my son started it the rpm's went to 3-4K. He shut the car off then it wouldn't restart. We put the orginal maf back on and car still wouldn't start. We let it set all night and this morning it fired right up. However when he was driving it it revved up on him again and wouldn't go down. Hope this helps.
