95 Silhouette 3.8 v6 engine cuts out intermitently on slight left hand turn and between gear shifts. If I let up on the gas pedel slightly and then back down on it it seems to help. I have replaced the throttle sensor. It''s worse in hot weather.


Dealer said I have to wait till somthing goes out.


Have changed all the sensors, plugs and wires, coils, computers, fuel filter, fuel pressure regulator, injectors, and the compression is 150 on all cylindars.


Thanks for any help in advance.

I just found a bad connection. Haven''t had time to repair yet. Pull or wiggle the wires on the engine side of the PCM pass thru harnessplug"All Data c111". Do this when the engine compartment is hot. It turned the engine off. Must be a broken wire.[img]smileys/smiley1.gif[/img]

Found the problem. Removed the pass through plug C111 at the wire harnes on the firewall. Hard wired the passthrough to engine harnes.


runs good now.
