lraffe1 Posted October 14, 2008 Share Posted October 14, 2008 customer towed in 93 F350 with a just installed reman long block, with new aftermarket injs, O2 senors and several other parts. When i first started truck would not even idle. I found the iat was open I replace sensors and retested okay. I then checked timing and was out. I set timing and would start and idle, but not accel. I then replaced map because housing was cracked and threre was no change. I then replaced both remote module and stator. The truck will now start and idle and will preform one wot accel, on secound accel eng starts to falls on its face and acts like it is missing, but spark is okay on all cyl. I also checked timing at idle after eng acted up and is okay. HELP PLEASE Quote Link to comment Share on other sites More sharing options...

Bruce Amacker Posted October 14, 2008 Share Posted October 14, 2008 36 psi while running Is that under load? (40-50MPH, WOT) Checking it in the shop is a waste of time. Also, check fuel quality by taking a sample in a glass jar. KOEO and KOER DTC's? /forums/images/%%GRAEMLIN_URL%%/grin.gif Quote Link to comment Share on other sites More sharing options...
jaysonfordtech Posted October 15, 2008 Share Posted October 15, 2008 Do you have a test coil? I have seen the old brick eec 4 coils act like a plugged cat at times. Is TP sweep clean? Do you have a working sbds? There were lots of cool tests to pin stuff down on sbds. Quote Link to comment Share on other sites More sharing options...
lraffe1 Posted December 16, 2008 Author Share Posted December 16, 2008 sorry slow to give update I found problem by chance. when pulling truck out of shop trans cooler line broke and lost all fluid. when truck lost all fluid eng ran worse. after fixing leak and topping off trans fluid eng ran better. I then unplugged trans and engine ran fine. I ended up replaceing trans because it was wasted. Quote Link to comment Share on other sites More sharing options...
