Brian P Posted December 3, 2007 Report Share Posted December 3, 2007 Post what ya got. Old threads, advice you have given about common w-body powertrain issues and fixes, etc. I want to make a good sticky here in order to help answer questions, especially for newbies. Examples include: Symptoms, typical causes, fixes for: -3100 coolant leaks/intake gaskets -water pump failure - transmission slippage, whining on left turns - misfires - no-start - rough or hunting idle - exhaust leaks - bad catalyst - ticking anything else you can think of.

ns87 Posted December 3, 2007 Report Share Posted December 3, 2007 3.1 MPFI: Stalling: 1) OHM the fuel injectors first since they seem to go bad 2) If a couple are bad, replace ALL 6. The others will go bad soon enough 3) Bad injectors also killed my fuel pump (unless everyone disagrees) Broken Vacuum Lines If your cruise control / air vent selector doesn't work: http://www.w-body.com/forum/index.php/topic,61171.msg726378.html#msg726378 4T60 If the fluid hasn't been changed in a long time/or at all: Drop the pan and replace the filter. Refill the transmission with 1/2 new fluid 1/2 old fluid. Repeat in a month or two. Many people say just switching to just new fluid kills these transmissions Filter + Fluid cost me around $32 If there is a really really HARSH 3-2 downshift, the rubber elbow to the Vacuum Modulator on the front of the trans is broken. Or if the modulator leaks fluid, it is bad. Brake Light Fuse Keeps blowing The wiring harness running from the brake light switch is next to a sharp metal edge. It can chaff and cause a bad ground (blowing the fuse). Zip tie it away from that sharp edge Quote Link to comment Share on other sites More sharing options...

But on a serious note, some of those would be kinda hard to do this because theres SO many things that could couse them. Only thing you can do is basically a check list.

Robby1870 Posted December 3, 2007 Report Share Posted December 3, 2007 A checklist would be nice similar to what is in Haynes or factory service manuals. Quote Link to comment Share on other sites More sharing options...
joey b Posted December 3, 2007 Report Share Posted December 3, 2007 spark plug gaps and a diagram of the cylinder locations would be very beneficial. I hope this would be in just one topic that is free of garbage, useless conversation, and questions. Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 3, 2007 Author Report Share Posted December 3, 2007 spark plug gaps and a diagram of the cylinder locations would be very beneficial. I hope this would be in just one topic that is free of garbage, useless conversation, and questions. I hear ye! Also anything pertaining to electrical/electronics problems and fixes. Like Cutlass ECC, heat door problems, keyless entry probs, etc etc. I'll add more in a bit. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted December 4, 2007 Report Share Posted December 4, 2007 I suppose if you wanted I could get diagrams out of my 1994 service manual...? Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 4, 2007 Author Report Share Posted December 4, 2007 it doesn't have to be super detailed unless necessary. I don't want to get into step by step repairs at least in this coming sticky. Quote Link to comment Share on other sites More sharing options...
slick Posted December 4, 2007 Report Share Posted December 4, 2007 Another few to add: Leaky distributor o-rings and fixes for the pushrod and dohc variants, leaking LIM's and repairs, common poor running problems (poor spark, not enough gas, crank sensor, etc...).
