97 Sl2 Mis-fire Under Load
I have a 97 sl2 with 127k on it and under a load it mis-fire i check fuel pressure it's 36-42 from idle and when brake torqued. I also replace wires ,fuel filter and pcv . my next guess is fuel injectors because i think it's fuel related because all coil pack are firing ok. also has engine lite on for egr and cat-converter. i replace egr with two use ones with no difference, -- forty ------------------------------------------------------------------------ forty's Profile: http://www.autostalk.com/m48 View this thread: http://www.autostalk.com/t393656 |

Wires should be below 12,000 ohms. Are they? What plugs did you use? Do you have egr and converter codes? |

out is was a broken intake manifold gasket. Paul forty wrote: > I have a 97 sl2 with 127k on it and under a load it mis-fire i check > fuel pressure it's 36-42 from idle and when brake torqued.

Doh! Before your guessing costs you even more money and still doesn't fix the problem, please consider either having the codes read and/or getting a diagnostic performed at your local Saturn dealer. If it saves you from having to replace ONE part that you don't need to, it has paid for itself.
