If it runs well for a minute from cold it could be a "cold enrichment problem" or manifold actual pressure is too low so a vacuum check could be helpful. It should be around 18hg at idle and the same with no load at 2,000 rpm. If not the exhaust is probably restricted and whether it's the chicken or the egg the converter(s) will be or are junk. What did it run like before the head gasket and why did it need it? T scorpion1tds Novice Apr 27, 2007, 6:07 PM Post #5 of 6 (2526 views) Re: 2000 sunfire - surging Sign In the surging is when i start it and when i rev it up to about 1800 2000 rpm hot or cold does not matter it ran perfect before i did the head gasket as coolant was pouring out between the number 3 and 4 head bolt the machinist told me it was warped oh the surging also happens when i start the car but i can drive it and its ok just cannt figure it out Tom Greenleaf Ultimate Carjunky / Moderator Apr 28, 2007, 4:28 AM Post #6 of 6 (2518 views) Re: 2000 sunfire - surging Sign In In machining the head the cumbustion area has been rudiced by some and compression could be higher and manifold vacuum could be higher which would fool engine controls to adjust fuel mixture and may not be able to compensate. I'd still check for vacuum problems. Spray carb cleaner at gasket between intake manifold and head and see what happens. It shouldn't do anything different. If no SES light has lit yet it probably will. The info may be a clue but not the most accurate for the problem. Was the whole head checked out or just machined to be true enough not to leak anti-freeze again? A thorough vacuum check and compression check might find the fault in the absence of any visual faults. The common denominator here is the head. It worked before machining and doesn't now which leads to anything that can be affected by that. Do you have any idea on how much had to be planed off to fix the head.
