When the engine is cold the computer advances your timing and richens the fuel mixture based on what sensors or telling it, but as the engines warms it starts retarding the timming and reducing the fuel and also as the intake air temp rises, it does anticipating spark knock and emisiions problems. this is a nornal function but if it seems to drastic then start by checking for codes, cooling system, and just a good once over to make shure everthing is working correctly, like BILLYBOB said it could be lots of things, good luck DW

If it turns out that every thing on there is working properly, then contact WEBMASTER about a chip for your computer. DW

might need to give it a tune up and reset the timing. get it up to its operating temp disconnect spout connector and set timing to 10* btdc. might have a clogged cat or bad fuel filter. hows your tranny, could it be slipping after it gets warmed up?
