i was searching threads and found out some people had similar symptoms to mine but im not sure if i have the same problem... After sitting for a while (more than an hour) my car is hard to start, it starts up but then idles low and sounds like its having problems idling. i have to give it gas and then after a few seconds it just kicks in and its fine. when im driving theres no problems at all. its the hardest to start when i wake up in the morning. could it be the fuel pump? i just replaced the filter because i was having the similar symptoms im haivng now. it was fine for about 3 weeks then it started again. car's goin in tomorrow, not sure to tell them what to check out really? fuel pump isn't a cheap fix...i want rims! thanks... :'(

In my experience, as you've probably seen posted, my guess is that your car's starter is probably going if it hasn;t been replaced yet. As you did, I changed the gas filter, had the dealer take care of all the TSBs and had them analyze it all to no avail. Then the starter died on me at 132K miles. Replaced the starter and voila!, the problem has not happened again in 3K miles after happening to me on an almost weekly basis. So probably get ready for your starter to die in the next 2-3K miles.

cold start valve

 

has to do with the fuelinjectors not getting proper prime until u hit the gas. more likley the fuel pump. but could be as simple as the gas cap. yes the gas cap. try tightning it down a little tighter. push in on it as u tighten it.

 

whats that? sounds like it would be that.

 

 

im not sure where its located, but i know in my olg gti i had a similar prob and that is what it was. ill check my factory manual and get back w/ you

 

cold start valve sounds like something on a diesel. i think our car uses the iacv, idle air control valve which is located just below the t/b. has some coolant lines attatched to it for thermal detection. but a faulty iac would cause irratic idling. repeated reving of the engine.
