300 E Backfire at 3200 RPM
In need of help!!!!!!
Have a 90 300E in the bay that will not rev past 3000-3200 RPM. Backfires through the exhaust if you try to push it pass that point. The harder you push the accelerator the more it misfires. Sounds like the ignition coil, EZL, OR Crank sensor is breaking up.
Any help would be appreciated.
