checked for leaks all the lines seem to be ok. also i went to the store to get wires and plugs to see if that might help.after i changed em it didn't want to start at dumb me the contacts on the cap weren't in right the contacts in the cap are deep on these things .Of course the wires don't seem to be the right ones and they only had the cheap one so i got those.they didn't fit!The plug end stuck out like an inch so that was bad but i had ordered the bosch set.Maybe that will help,I lowered the idle so that helped also.It still seems to be affected by vacuum taking the fact that it gets worse when i use the headlights.the drivers side does come up slower but I'm not even sure if they are vacuum opperated I'm still stuck in vette world lol.I was Wondering do these things have a vacuum canister?

your headlights are electrical, not sure about the vacuum canister.

found the prob i wanted to find out if it was one of the sensors so i unplugged the tps sensor the up and down stopped so i think thats that.the only thing that it starts reving only after it gets hot so we'll see.Also do u guys think disconnecting the sensor just hides a vacuum problem i plan on getting a new one so i just wanted to know so if thats not it and the sensor is doing what its supposed to do in the event of a leak i would not spent the cash.
