I don't know what this could be but when I start up my truck sometimes it roars to life then chuggs down to somewhere around 500 rpm and occasionally dies. when it doesn't die it revs back up to 1000 rpms and it dives back down then it goes to perfect idle. it is wierd. It just started this after I put on my NOS system. I don't think this is the prob though because it doesn't always do this. could I have a regulator problem or what? I did have to have the fuel pumps replaced because of a stupid problem where the rear tank didn't return the fuel there but to the front one and over filled it.
any help would be greatly appreciated.
Thanks Chris.
