Engine Performance problem
1997 Ford Escort 4 cyl Front Wheel Drive Automatic 49000 miles
This car recently had new muffler installed. Sluggishness from dead stop noted shortly after along with what almost sounds like an exhaust leak in the front end - returned to shop and no leaks found. Once up to highway speed, car runs fine, however once warm the car idles rough (surging) when at a stop. Turning the A/C ON cures this problem so long as the fan runs (30 seconds). When the fan shuts off, rough idle returns. This rough idle sounds like a cycling 1 second surge in RPM. Rrrrrunh, rrrrrunh, rrrrrunh
New plugs, wires, fuel filter, PCV, serpentine belt installed. Sluggish acceleration improved, but could be better. Rough idle after warm-up continues.
Temp gauge flaky, accurate when working, but cuts in and out. Seems to be affected by acceleration and shifting between gears. Either reads correctly or not at all. This is a fairly constant state, IOW it fluctuates every few seconds rather than minutes or days.
have the same problem?
