I thought a full tank would help but after I filled the tank, the problem has WORSENED. Its very difficult to start it now as it knocks like crazy. The car idles smoothly sometimes esp. before engaging the drive gear, after that it simply stalls. If the filter is clogged then the car would not start at all. Right? Please suggest. Thanks. check to see if your fuel filter is clogged..also might need a fuel pump
all engines hesitate when cold they need to get to proper running temp
It can be battery, faulty coolant temperature sensor, faulty cold start injector, malfunctioning fuel system, injector leaking.
It sounds like you have water in your tank. Use dry gas.
People that have the common cold would be a good place to start.
30 psi, when it's cold.
It is most likely the mass air flow sensor that is going bad. I had a similar experience and replaced the maf and that did the trick.
There must be a restriction within the intake. Snow? ice? Mark
Cold Start Valve. Cold start valve. I do not believe there exists a "cold start valve"
It could be the Tw sensor , or ur fuel enjactor dirty
Have your battery tested. It could have a bad cell in it or not enough cold cranking amps. This is a simple fix. Batteries usually start about $40+. That is what I would do.
check igntion coils
