Surging at startup

[rvs9]

My H2 has approx. 16k miles on it. Last couple of weeks, when I crank it up after driving (i.e. engine is warm), the engine surges for about 10 seconds whether it is in park or drive. Doesn't do this in the morning when first cranked up. Anybody else going through this?

I did at about 31,xxx miles and the dealer "for a fee" cleaned the injectors and replaced the fuel filter. no more problem

When an engine surges it is most likley a vacume leak. Look for that,better yet just take it to the dealer for repair. The warranty will cover it. BIG-C

I have noticed mine doing the same thing. The RPM's go up and down like a roller coaster when first started. Let me know if Kelly Hummer fixes it. If that's where you got your H2 that is the dealership mine came from.
