Yeah i checked my TPS wiring before that is how i found out it was bad andafter it was good. It could be my temp sensor though couldnt it? I mean it seams like all this would throw a code but ive checked and there isnt any cies? do you think that my ourge valve/evap canister could do this also? if this is bad it wouldnt throw a code also what size are most of the vaccum lines? there isnt very many vaccum lines i thinbk im gonna just replace them all as it will be cheap and just as fastr as checking them thanks

 

Changing vacum lines is a good ides but I don't think the AC system problems you're having are related.

 

you dont think vaccum lines could contribute to the bogging down problem? do you know what size the lines are by any chance? thanks

 

i know the one coming off the brake assist if it comes off my truck runs like crap. it could be a vaccum

 

Sometimes it is better to take it to a qualified technician to diagnose then through parts at it. In the long run you will save money letting someone with experience check it out. The evap canister or purge valve WILL NOT cause your problem

 

ive taken it to two mechanics both said what it was and when they thought they fixed it same thing happened on the way home from the shop. I spent more money at the shop then i did throwing cheap sensors at it the only thing i havent replaced is the temp sensor and the map sensor. i checked the map sensor and it was good seams like both of these would throw codes. Cleaned throttle body, ran sea foam through it also.. what else could this be guys?

 

take it to the dealership. I've thrown a lot of money at things b/c i didnt have the right diagnostic tools. I'm sayin vacuum leak
