Have you checked the EFI for any fault codes?

I'm getting a code 43 now after replacing the idle air control and the tps. Code 43 is suposed to be either the tps or a faulty ignition control module, but I just put a new distributor and control module in 4 months ago but I took the control module out and had it tested and it tested good. I can't find any vacume leaks either. The truck runs great anywhere above idle.

First of all, check connections - wiggle them w/ vehicle running. Check connections into the computer. If the TPS is adjustable, that may be problem also.....

 Finally figured out the problem, It was the "new" distributor I put in from Advanced. Got another one yesterday and it runs better but I still get a code 43 every once in a while but the light does not stay on all the time anymore... Moral is don't buy a distributor from Advanced.

I have 90 K5 Blazer and a strange problem I can't figure out. At idle, the truck's RPM will slow down then pick back up, it's not that noticable in park but when I put it in gear it's really noticable, some times it will even stall. The truck has a TBI 350. A friend on mine said it might be the TPS, does anyone have any information on how to check this? Any help will be apreciated.
