1992 245 (LH2.4) Idle Problems, Missing, Rough Running,At 1000rpm+ Runs Great

93Regina,

I haven't checked the fuel pressure yet. With the engine running at idle, there's no change whether the FPR is engaged or not, cold or hot engine. I've checked the diaphragm for a vacuum leak and it's good. Will check fuel pressure.

Well when I took it off and plugged it, engine smoothed out a little? Sorry for hijacking thread but I’m having same problem and I’m about to go nuts
