Car running weird

[bansheenut420]

Its been the same with 2 computers, its not a computer problem.
wiring.

92/93 have 2 heat sinks, 91's have 3 heat sinks.
and like the others said, if it did it with 2 different ecu's, then it isn't the computer, it is likely a wiring issue. Did you try the suggestions I gave you last week?
Thanks,

Try running some new grounds from the battery to the block and to the firewall. Also when the car is idleing bad, pull each injector plug and make sure it makes a difference, if one doesnt change the idle for the worse theres a problem there. You can also do the same with the spark plug wires. You can at least isolate spark or fuel and which cyls.

Ya I tried them but no luck but I am trying a couplr things right now I'll let you know how it go's

Ok when the cars starts to idel I pulled #1 off and no spark then it will kick in and shocked the piss out of me!!(not funny).While the cars running it will run good and have good fuel pressure good spark/fuel.I notice that the car runs lean at idel with my wideband like 18 plus not even showing up on the gauage it's that lean.But when the car runs good and I get into boost it goes to about 10 11 to 1 on the rich side.The cal part of fwd's works great I mean really good besides I can't check codes for some odd reason but did before.Is the anyone in ohio I could try my ecu on to see if it's the ecu's fault?.I really hate to keep sending my ecu back and forth costing to much money because I hate to wait on things and overnight is being a pain in my a**.So thats what my cars doing so keep the suggestion coming one of them will work.

I tryed running a new grounds to all the factory grounds to the battery but no change.This car is very picky but hopefully someone lets me try my ecu on there car and I can go from there.Cindy I think I will have to borrow one of your's if you dont mind and I'll pay ya for your help and where you didn't have another 92 computer to send me and caled mine and sent it back problem still there so I think it's the ecu itself

Get some NEW plug wires on it! IF you were holding the boot or back on the wire, and it shocked the piss out of you; You have BAD plug wires. If you check it in the dark, you will probably see sparks from the plug wire to the head when it's missing.
Bring it up to Barberton, We will fix it. I have a good used set of Magnacore 8 or 8.5mm wires.

Check the cam sensor gap. Also check the coil connector. Id pull the pins out and make sure they are making good contact on the coil. You might put a dab of di-electric grease on there. Did you say you swapped a coil? Is it the same cyls that go dead each time?

[boostedhatch]

Yup a brand new coil.How much gap is there supposed to be?.It's been the same cyl every time so still messing around with it but I'll check those

[mopar2ya]

about .015. Take a sheet of paper and fold it in 4ths, that will get you close.

pull the injector harness and check each lead. I'll bet that you have wires shorted together somewhere. I found mine shorted inside the plug where wohoever mad the harness.wrapped the wires around each other intensionally so that they melted when they got hot. It really looked like intentional sabatoge.
