John/Horace Posted December 15, 2020 Report Share Posted December 15, 2020 Always scan for codes first before throwing parts at a car. Like already mentioned plugs are technically still not due yet. Could be map sensor or 02 sensor etc and not plug related. Quote Link to comment Share on other sites More sharing options...
Gordy2 Posted December 15, 2020 Author Report Share Posted December 15, 2020 Thanks to all who for the information.Plugs will be done later then.I will have the map and 02 sensor checked. Quote Link to comment Share on other sites More sharing options...
2late4u Posted December 15, 2020 Report Share Posted December 15, 2020 might be the throttle body is dirty as well Quote Link to comment Share on other sites More sharing options...
