So yesterday I noticed that my pony was unwilling to start up when cold. The crank times was about 5 secs which way longer than usual. Starts up quickly on a warm start though.
I checked the battery and it shows 12.53 volts when the car is off.
I don't know how to check the started but I don't hear any knocking or ticking noise when cracking up the car.
I have a brand new fuel pump assembly, fuel filter and fuel pressure regulator. I have 37 PSI at idle. I also have new sparkplugs, wires and coils. The IAC is also new. No leaks in the cold air intake system.
My car hesitates when running steadily in 2nd and 3rd gears between 1,5 - 2.5 k rpm.
Today I opened the hood and noticed that my PCV hose that goes from the passenger side valve cover to the upper intake, has oil on it right where it connect to the intake (90 degree bend part. Could that cause a bad cold start and hesitation? I would assume that leakage causes unmetered air to get into the system.
thank you for the response. It turns out that my battery is not holding the charge. Today it did not even crank. My friend jump started me and the car was running great, both, at idle and under various loads. Now I need to replace the battery. Any suggestions for a good one and yet not too expensive?
