i posted a month abo about it not starting ...it was the ful pump....but now im having another problem.......it starts fine and runs good but as soon as it warms up it starts running like crap.....it didnt do this before

 

Egr valve might be sticking open, make a block off gasket out of a soda can & sandwich it between the valve & the gasket. Then drive it for a couple of days & see how it goes.
You might have a bad coolant temp sensor, it acts up when its hot. You'll need an ohm meter to check it.
You might have a heat related issue causing weak spark.
Any codes?

 

Plus check the idle control valve, AIR pump etc. etc. etc. etc. Sadly you'll probably just have to work your way through everything unless you've got specific codes.

 

ill get my uncle to scan it monday......it smells like raw fuel when its running as well...

 

Check the fuel pressure & leak down rate, you might have a bad pressure regulator.

 

ok i ulled the codes it threw....i got one for a tps and knock sensor.....could they be the problem?

 

could be. What were the codes?

 

what ever the codes are for the 2 things above...my uncle checked it out for me yesterday
