Question about 1989 Ford Mustang
The ol stang runs good when it's cold .
when it's hot she has problems , after driving it till hot if I shut her down for a minuite and start it up again it turns over slow but still starts fairly easy in addition to this my rpm's are slightly lower and when accellerating it gives sort of a stumble or a miss and a very noticable but un steady knock coming from what sounds like the rear of the car.
after a couple of minuites it quits missing but has the knock after the initial load while accellerating seems to lose 15-20 hp from it's colder running state. car is all stock with new exhst front to back, battery, alt, fule filter,and I run premium gas.
check engine light is on with codes 32 and 82 extracted passed e-test.
any info would be a big help,I'm a chevy guy trying to have faith in an old ford. hope it don't see the boneyard any time soon.
That could be coming from a couple of places. first thing I would do if it is an automatic tranny, replace the tranny filter and flush the fluid. If that is not it, check the intake/exhaust manifold gaskets. One of these could have rotten out from old age. Finally, if once the engine heats up, if the oil pressure drops dramatically once the engine is warmed up, rod bearings and main bearings have gone out on it.
