Try a TPS, throttle position sensor. It both advances the spark and increases fuel pressure when you push down on the pedal. If the TPS does not repair it, then use a water spray bottle around all the intake manifold seams while the engine is running.

If you have a intake manifold gasket leak the engine will pull in the water and change the RPM. An intake leak will throw off all the settings and cause hesitation.

Turns over will not start. have alread changed the spark plugs dis. cap and rotor. Could it be th coil? or a fuel system problem?


First check for spark at any of the sparkplugs.If you have spark then it is more then likely the fuel pump.You can'nt check the fuel pressure unless it is running.The fuel pressure is suppose to be 38-44 with the engine running.

My 2002 taurus is hesitating so we tried gas treatment and replaced fuel filter...it's better but still hesitates and idles rough. What's next to look at?


When using gas treatment, it's a good idea to pull the spark plugs after 500 miles. Most engine / gas cleaners are effective but the impurities burn off on the plugs and they can become fouled. Another place to look is the distributor cap and rotor. A tiny crack in the cap is all it takes for an engine to run rough. Lastly, inspect the spark plug wires very closely. Look for any bare spots and ensure that they are tight both at the spark plug and at the distributor cap.

I am having hesitation when start of acceleration. Already changed plugs, fuel filter


I had the same problem. New plugs, wires, fuel filter, air filter, MASS airflow sensor cleaned and still it would hesitate. It seemed to get worse when warm. Sunday I fixed the problem. Take the distributor cap and rotor off. Under the rotor there is a metal plate held on by two screws. Take the plate off, this will expose the optical Cam sensor. I took a can of MASS airflow cleaner (Plastic safe)(can buy at advanced auto parts) and sprayed heavily. Once it was dry I put it all back together and it runs like new.
