If it makes you feel any better, I have a misfire too now. Mine only happens at a cold start when it is cold outside.

Dunno, just thought I'd throw out a cheap and easy thing to check.
I'll try that ... thanks

Popping is a symptom of a lean condition... could be caused by a number of things from MAF to TPS to 02's to dirty fuel injectors.

If it's bad enough, this can internally damage the engine (lean = hot)

Actually it makes me feel worse .... what I need is an app to measure engine smoothness ... that way I can twiddle with stuff until it smooths out

Same issue with my '98 D90. Turned out to be slightly corroded contact points in distributor cap. So replaced it, the rotor, and since we were pretty sure a couple plug wires were fubarred as well replaced all plug wires. Problem solved. Might want to check.

Interesting. Your 98 has a distributor?

Don't be a hater! Pretty funny actually. Might have to go look but last time I checked it was a '95.

Hold on a sec . . ..

Yup, it's a '95.
