Venom Posted June 7, 2008 Report 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

Breakdown Posted July 1, 2008 Report 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
