Hesitates when at half throttle for a while, then comes back without position change.
Hey People,
This one has me stumped, anyone ever hear of this?
I have a 1987 Jeep Cherokee 2.5 liter 4 cyl with a throttle body injection system.
When I am driving at about half throttle, the engine hesitates for a second or two, then comes back to life without any change in throttle position.
It doesn't do it when the throttle is floored or when it is coasting with throttle off.
The problem is intermitent and it runs and idles fine the rest of the time.
I have already replaced the tps sensor and have done a full tuneup including the fuel filter.
It seems to get worse when it is hot out.
Any ideas?
