You need to turn off the Overdrive switch.
Bad transmission if auto Bad clutch if std.
depends on the transmission. auto = bad trans. manual = bad clutch
I just had to do this in order to replace my water pump. If you're not mechanically inclined I'd strongly suggest you have someone certified set the timing. Since then my 91 talon revs up and down as long as it's running. I just bought an Idle Control Valve. I hope this will fix the surging. There are notches, or timing marks located on the sprockets that have to be accurately lined up in order to set the timing. hope this helps.
The best thing about CEL's is that they can point you in the right direction for repairs. Even though your light does not stay on, it's likely the computer has thrown a code to the memory. To find where to start on repairs, run the codes.
A vaccum Leak
Possibly a stuck or sticking EGR valve.
1993 eagle talon top speed 2.0LMy FWD 1993 Eagle Talon ES (2.0L DOHC) would go 124mph going straight and flat, no wind. With the benefit of a tail wind, I've had it up to 127mph. That's drag limited and all it's got. This is in 5th gear; shifting into 4th slows the car down as the revs are too high. BTW, this is top speed as measured on a GPS (not via the speedometer, which is inaccurate). I believe my particular speedometer would say 129 at 124 mph.Only mod is opening the air intake box and installing a K&N filter.
You might have a dead cylinder or a misfire in one of your cylinders.
If it is running fine at high revs the most likely problem is an injector
Check your radiator is full
Check the Idle Air control valve. This lets air bypass the throttle body plate when the car is at idle or low revs.
Yes it does, mine has exactly the same problem, can be the MAF sensor, fuel pump problems or the idle sensor. just changed the MAF on mine saw some improvements but still revs up and down occasionaly
