Question about 1999 Chevrolet Venture
I have a 2001 Chevy Venture and recently had the thermostat replaced, once it was done the van still starts great but now when I break at a light you can feel the van hesitating and when I'm on the highway you can feel the van hesitate and you think its going to stall but doesn't. Sometime when I put the car in park you can hear and feel the engine hesitating.
There could be several reasons for this type of problem. the engine is controled through main computer(ECM) and the sensors assocciated with it. most often times a hesitation is commonly a idle issue and that would be monitored by the TPS ( throttle position sensor) if this is beginning to fail it sends faulty reradings to the computer and the computer tries to compensate and sometimes either leans or richens the fuel air mixture cause and effect is a engine stall or a hesitation. another factor is your (O2) sensors these monitor your exaust and tell the ECM to adjust accordingly the fuel mixture also. a sure fire way to tell if one ore more sensors are faulty is to either have your check engine light come on or if there is a rough start. if the check engine light isn't on then i would think there is a timing issue involved and a tune up is in order. the tune up is simple by just changing plugs and wires, however the timing is computer controled and can only be adjusted by a certified tech with the proper equipment. try and change the plugs and wires first this is the least expensive way to solve your problem. if the problem persists then take it to a shop and have a tech hook up diagnostic tools to check the ecm for fault codes to narrow down whatsensors if any are faulty.
