My 95 E320 engine misses at both idle and under load. It just started. I replaced the spark plugs which were quad plats with Bosch copper cores. No change.

The car is still under StarMark warranty .... I rather not pay for exploratory fees ... something I've been charged for in the past.

I searched through the forum and didn't seem to turn up anything except a possible bad throttle body?

Thanks in advance for your help.
