1998 chevrolet silverado 1500 hesitates or chokes when accelerating. When the engine warms up the problen seems to be a little better but not totally gone altogether. I put 1 can of berriman's fuel and carb cleaner with a full tank of gas and that temporilary seemed to fix the problem until I filled up with a new tank of gas. Thanks

There is a throttle valve positioner sensor located at the end of the throttle valve shaft on the right hand end of the shaft, the sensor then bolts to the throttle body as you face the engine from the front. A defective sensor will set the check engine light and give hesitation during acceleration.

Fuel filter clogged, weak or faulty fuel pump. Have fuel pressure checked, if its ok, then check igniton coil or module.

need to check your fuel pump pressure, should have 55 psi, these trucks are bad on fuel pumps

Sounds like a o2 sensor, if you don't have a check engine light on, you soon will. The PCM can be scanned to find out which one is faulty.

1 check spark plugs if the seem old corroded rusty black then replace them asap....check fuel filter maybe clogged ....fuel type might be a factor too .... need more info buddy

u need a choke adjustment - it is simple and not very expensive - look under the hood - take the air cleaner off - if this is an all electronic engine it can be tricky to spot but there is a choke adjustment --
best for a shop - not over expensive - also
while doing this - take down the vin number and call the local dealer and ask about recalls

Your dealer will take care of it. That is the very best advice I can offer. Good luck to you..

I would have the computer scanned ( no SERVICE LIGHTS right ? ) looking for an errant coolant sensor not telling the computer to give your vehicle a bit RICHER ( a little bit more fuel ), since it does start. Just has POOR cold drive away. Hope this helps

Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?

Some of these have two temp sensors, one for the gauge, and one for the computer.
