Stimmel1647545512 Posted August 14, 2010 Report Share Posted August 14, 2010 I have an 88 mustang 5.0 5 speed that has been acting up the problem is that at extended idle it starts to run poorly any help with any of these codes and where to start fixing them? 67 81 82 85 Thanks Quote Link to comment Share on other sites More sharing options...
rl Posted August 14, 2010 Report Share Posted August 14, 2010 Do you have any smog equipment on the car? Thats what 3 of the codes are for (Evap). The other is a neutral saftey switch code, it might have asked you to press the clutch during the test and you didnt. None of those codes should effect driveability. I would check for vac leaks, what MAF is on the car? it sounds like its pegging the trims after a long idle. Quote Link to comment Share on other sites More sharing options...

rl Posted August 15, 2010 Report Share Posted August 15, 2010 Your MAF randomly swapped itself in a Wendy's drivethrough? I'm no expert, but that could be the problem. I'd check for intake leaks. Quote Link to comment Share on other sites More sharing options...
