My 93 tracker has started acting sort of strange... Every now and then when I hit the gas and try to accelerate out of a stop the engine will actually slow down for about 5-10 seconds before picking up and actually accelerating. A couple of times it's been so bad I thought it was going to stall, but so far it hasn't quit yet. Compression test is 165-170 on all cylinders, timing is between 8 and 10 * BTDC, I've got a cone filter on the intake, and a Thorley header piped into a high-flow cat and cherry bomb muffler. Am planning on doing a valve adjustment this weekend.
The hesitation is always in the lower gears, although the highway speeds aren't quite as good as they used to be.
Any ideas?
