Slade901 Posted June 22, 2003 Report Share Posted June 22, 2003 When was the spark plugs/wires replaced? Don't forget to clean the throttle body intake with a throttle body cleaner. That should get you started.. Next would be to check the coil packs.. Use fuel injector cleaner every oil change... Quote Link to comment Share on other sites More sharing options...
ismellrealbad Posted June 22, 2003 Report Share Posted June 22, 2003 Use fuel injector cleaner every oil change... really that often? i heard maybe once or twice a year otherwise it might do more harm than good Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 22, 2003 Report Share Posted June 22, 2003 A new O2 sensor really helped my idle out, as well as clean PCV, TB, intakes, the whole works. However, what has been mentioned is a good place to start Robby Quote Link to comment Share on other sites More sharing options...
silver_92_z34 Posted June 22, 2003 Author Report Share Posted June 22, 2003 hay thanks keep 'em coming I cleined the intake and TB last week with top engine cleaner. the O2 is alittle old but not factory. I did see a tech bulitin on low idel having to do with PROM programing, so I ordered a FFP chip it should be in soon. I had a resistance test done on the wires and they are good and the plugs have 8,000 miles on them. I think I will try a PVC although top engine cleaner should have done the trick( and it dose rattle when you shake it). Thanks for your suggestions. I'll let you know if the chip is it.

Robby1870 Posted June 22, 2003 Report Share Posted June 22, 2003 oh, something else I fought for a while was a bad TPS. It made my idle sorta rough. Got a new one (since ours cant be reprogrammed), and that helped a lot. Yeah if the PCV still rattles its good. Robby Quote Link to comment Share on other sites More sharing options...
Slade901 Posted June 22, 2003 Report Share Posted June 22, 2003 Use fuel injector cleaner every oil change... really that often? i heard maybe once or twice a year otherwise it might do more harm than good If you are using the highest octane then usually you will just need fuel injector cleaner maybe once a year but some people I know they always use fuel injector cleaner every oil change as preventive maintenance (to remove any gum substance that might develop in the fuel injectors.
