Ok so i start my truck everything is normal, but when i give it some gas, maybe 1500 rpms or better it will start hesitating like it needs more fuel, well i cant drive it down the road because i have no power and it doesnt want to go through an intersection, i cant floor it that doesnt solve anything, giving it less gas has the same effect as more so im more at loss of what to do right now. i thought it was a vacuum leak so i just went out and checked all the vacuum lines. bear in mind it has a new tps, and new fuel pump assembly

 

Remove the front O2 sensor from the exhaust, see if it runs any better.

 

ok will try that later and post results

 

make sure u leave it connected.... just unscrew it from the exhaust

 

ok so i found my vacuum leak and found a new issue i wasnt aware of yet, it would appear the i have some popcorn sounds under my hood probalbly from the throttle body what would cause this?

 

ive found two rotting hoses that were cracked and have replaced both so ill see if that helps any i checked my cap and theres no obvious cracks in it just slight white oxydation on the points.

 

still unsure of the popping from under the hood?!!

 

Any chance you have tried unscrewing the o2 as suggested?

 

popcorn sounds are normally spark knock (pre-detenation). that would be caused most likely from the plugs. might be due a tune up.

 

zman i havent had the chance its been raining here and i dont have a dry spot to get under it yet

ryan- i had just done a tune up, plugs,wires,cap,rotor button,coil, is it possible that a plug could be fouling and not working right
