'94 TBI 4.3L Acts like running out of gas. HELP!
 

Drives fine for a like 2 min but as soon as it gets warmer it acts like it is out of gas... I know it is not. The first week I had it it ran great and everything. Then one night it started running bad. So I did the Engine light flashTest thing and it came up with TP sensor So i changed it and it fixed the lurching when put into gear but now after it warms up it jumps again. Also it idles up and down in park the oil pressure goes up and down. Also the check engine light continues to stay on and it always says the TP sensor.... What could it be? Something just ain't right. Thanks for reading.

Sorry never saw your other post. But as long as you have oil pressure don't worry about it. it should just follow the revs unless the oil pressure just randomly jumps around and isnt in sink with the revs then worry. When was the last time the you did a tune up? and you might want to do the fuel pressure test cause i dont think lurching would be caused by vacuum lines. Mine has had bad lines and it just caused a bad idle. And you have to rest the car, take the battery off and wait for 10-15 minutes and put it back on. See if it goes away.
