Post Fuel Filter Woes

[Sully]

After doing the fuel filter, starter, and adding dye to the radiator, I took the truck for a drive and it was awful. When coming to a stop, the RPMs kept dropping into the 400s and it felt like it would stall out anytime. Other that stopping, however, the truck ran much smoother than in its pre-filter days. After searching the forum, I know I need to recheck my air hoses. Also, the TPS could be off. I came across a post that stated that it could take up to 15 starts for the computer to reset or adjust itself (hopefully not like CDan's avatar). The post was mostly just a teaser. Could someone elaborate on this?

My experience is the same - either after disconnecting the batt cable or pulling the EFI fuse. Rough idle, funny behaviour at start up. Just takes a few cycles but I've never had it take more than 5 or 6. I would first make sure you've cycled it several times before worrying.

Pull off your tps and check it against the fsm with a meter--this sounds like what I was experiencing. Also if you haven't cleaned your throttle body you should--it makes a world of difference.

AS MoJ said, definitely could be the ECU re-learning your parameters. Might as well check all the air hoses right away too (as you said) since you've been messing around in there. If it persists, move on to Sr. Gringo's suggestions.
