Have a problem with my Bmer! When I step on the gas pedal, there's a hesitation on the engine! It seems the RPM had a hard time reaching the 2-3000 mark!!! But sometimes it doesn't do that!!! When in idling, it seems everything is OK!, but when you step on the gas pedal, engine runs rough, kinda misfiring and popping sound..
I already checked coil packs, throttle body, TPS, Airflow sensor (MAF), manifold hoses....replaced Plugs, new valve cover gasket, done oil change, new fuel filter and replaced a/t fluid.
Read about cleaning ICV...but can't find it's location?
When I drove the car, it seems that fuel is not reaching the injectors...but the car never stall/s! Its not hardstarting either.
Tried to check the fuel pump! when i removed it, the pre-filter at the tip of the pump was cut open....dirt went inside the pump which cause the hesitation.... Replace the fuel pump and the problem was GONE!
