The vacuum leak is the key to your problem, use a can of carb spray and find out where it is. Anytime air leaks into the engine that does not get metered by the MAF sensor then a lean condition will be caused, this makes the engine hesitate.

My 2011 corolla hesitate's while driving. The problem usually occurs when I'm driving 40mph and only last for a short period of time, but constant. It never shuts off but loses power as if I


Sounds like a throttle position sensor. It is a variable resistor that moves with the, "gas" pedal. What happens is it wears out in the position it spends the most time, say 40 mph. Then it can't properly report the position of the pedal to the car's computer, it looses connection, and the computer thinks you just let off the pedal completely, and the engine goes to idle. A slight movement of the pedal goes to a less worn spot, and the fuel flow comes back to the engine.

My 1997 Jeep Grand Cherokee Laredo is starting to have a ''slight'' hesitation after I shut it off and re-start it again. WHen I accelerate at first it hesitates a bit. I let off the gas for a few seconds...


A slight hesitation after engine shut off due to engine running rich meaning not meeting golden air:gas ratio of 14.6:1 so fuel residue in chamber continue to burn for the last moment. The same rich fuel problem that was why you had to let gas off during acceleration. Need to Check out the O2 sensor Check out MAP sensor Good luck

The upper intake gaskets may be leaking. They are made of plastic and metal and will leak air. Do not remove the cover on very top of manifold when changing.
