Venom Posted June 7, 2008 Report Share Posted June 7, 2008 You could always spray some water around the plug boots and at the coil packs. If it starts misfiring worse, Then you might need to do a tune up. Quote Link to comment Share on other sites More sharing options...

Breakdown Posted July 1, 2008 Report Share Posted July 1, 2008 I'm getting codes 32 & 34 32: EGR System: Check vacuum hoses and connections for leaks and restrictions. Replace EGR valve. 34: MAP Sensor: My heart was racing there for a second. I wasn't far off though, error codes: 32 & 44 means that the car has started it's auto-destruct sequence, not far off, I read up about this while at a car museum, something about the cold war. EGR (in my opinion) will be effected more at lower RPMs not cruising. Quote Link to comment Share on other sites More sharing options...

EGR (in my opinion) will be effected more at lower RPMs not cruising. EGR, if stuck open, will cause a huge vacuum leak at idle. Quote Link to comment Share on other sites More sharing options...
