91 stealth twin turbo. I have a misfire on cylinders 6 and 3. I have had the ecu rebuilt 4 times twice by ecu exchange twice by Avpro. I have switched coils around and same 2 cylinders dont fire. Any help would be appreciated.

 

Ignition Module
Sometimes when you are having ignition problems, it narrows all the way down to the actual ignition module. If you are not getting any spark on any cylinder, this could be the culprit. This OE module (its located below the ignition coils). Only for 1991-1999 DOHC TT and NA motors (not for SOHC engines).

 

Problem us probably bad connector. Try bypassing the connectors, see if that helps.

 

I had a misfire in my 1991 RT 10, the ECU showed no leakage and the vehicle only had 8,600 miles. My mechanic tried everything and the dealer where I purchased it new in 1991 would not even try. I read a post on a web site regarding the ECU, had mine removed, sent it to have it rebuilt, even though you could not see any leakage or damage, and that cured the problem. Actually, the car runs better that it ever did because the rebuilder updated the program.
