hesitation

I have a '94 sport with the 4.0 L and ever since I bought it, the throttle has hesitated for a half-second or a little more. The motor bogs down for a moment and then revs up. This makes hills a little difficult with the manual transmission! I end up having to side step the gas from the brake pedal to compensate for the hesitation. Could this just be a sensor all outta whack somewhere? vacuum problem (I just redid my intake manifold gasket and had to disconnect and reconnect all the vacuum lines on the intake and they looked fine) perhaps? Mixture? could it be linked to a lack of power and a gurgling noise when under load? One more thing, when I'm on the freeway and have to downshift to 4th to go up a hill, the motor just stops accelerating at about 2800 RPM. it's like hitting a brick wall. I'm assuming there's no rev limiter as I've managed to rev it far past that in, say, first gear.

Re: hesitation

I don't know if you ever got this fixed or got rid of the vehicle but I just picked up a sport myself that had the same problem. I disconnected the MAF sensor and it ran great. If I hooked it back up I had the same problmes that you have. I was told to take the MAF off and clean it with throttle body cleaner. I sprayed it really good and if fixed the problem. If that doesn't work you may want to replace it. But try unhooking it first and then revving it up.

Re: hesitation

Thank you very much for the reply, however it's about a week too late. In the process of testing the MAF with a multi meter, I took it out and cleaned it off just because I noticed that it had crap on the resistors - runs the best it has since I bought it now! Thanks, though, your reply made me feel alot better about it because I was only surmising as to what I did to fix it!
