ByTheSea Posted February 13, 2004 Share Posted February 13, 2004 Car is a 95 Imp 2.2 NA auto trans 125K. It recently started to backfire when accelerating from low rpms but only after high rpm use. I'm goigt to do the plugs and wires. Is there any major issue other than that to look at? Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted February 13, 2004 Share Posted February 13, 2004 I think if you unplug the MAF sensor you will return to open loop mode using the ECUs default air/fuel ratio. If the problem gets better might be the MAF. Quote Link to comment Share on other sites More sharing options...
