    cold start problem

    I searched for a good 10 minutes, but couldnt find a problem exactly like mine. If there is, point me in that direction, please.

    I've got a '90 LX Auto. Whenever I cold start my car, especially in the morning (50 degrees lately) I have the following issue. The car will crank more than usual (about 3 seconds) then barely fire. It'll "catch", the rpms will be around 500, rough vibration...all for about 5 seconds, then the rpms shoot up to 1500 and then come back down as it warms up. (shooting up to 1500 is typical of my car, and probably others?)

    I thought about cleaning the IAC valve, but I'm not having a rough idle when the car is warm. And I might get some help from cleaning the FITV, but my problem is more about a rough start with low rpms at first.

    Any help needed!

    How are the spark plugs? I know I changed out my plugs with a set of crappy plugs and it started being real difficult about starting.

      check spark plugs and Sp wires.. also check distributor rotor for carbon tracks.. also make sure non of your fuel injectors are leaking.

        Does it spit a CEL when it gives you a hard start? I just had that problem and it would be very difficult to start in the mornings. It ended up being the distributor.

          I know my spark plug wires are okay, they are fairly new.
          And the CEL hasn't come on recently

          I don't know about my spark plugs, but if those were bad, wouldn't i have more trouble than just starting?

          I know where the distributor cap is, but how would I go about checking the rotor for carbon, or how would I tell if the fuel injectors are leaking?

          Another piece of information that might help find the problem, is that on really hot days, when the car has been sitting in the sun, I can't start at all. But i've always thought that had to do with the main relay being too hot, and would be totally unrelated.

          Thanks for the help so far!

            Carbon on Distributor - Remove wires and cap and check for white stuff.

            Injector leaks - check the injectors if they smell gas
