Alright, so yesterday on the way home from work my truck started puttering at the stop light, like a misfire, but drove fairly normal. it hesitated and started getting worse on the way home. Once the wife got home I went to autozone and got some bosch platinum plugs and wires, and fuel filter. I changed all that and took her for a drive, seemed fine. today on the way to work everything was fine until I got around a hill and it was kind of surging and started running like crap again. after work I checked all the plug wires and everything was good. started it up and drove to pick up the wife and it started getting a lot worse. its stumbling/puddering at idle and surges while at a constant throttle.

No codes are popping up. I changed the wires around and its still doing the same thing. All the plugs were gapped and Im kind of stumped. I did manage to break the vaccum line from the fuel pressure regulator to the top of the intake but I did the redneck temporary fix with some electrical tape.


WTF the truck is close to being pushed off a cliff

Thanks for the help in advance and sorry for the long post

 

fuel pump is going out.

 

x1. and take those bosch plugs out

 

I just replaced the fuel pump maybe 3 months ago with a new GM one...possible though

 

I did run some heet stuff through thinking it might be that but that was before I changed anything and it wasnt acting up... it would throw the p0171 and p0174 codes so Ive been trying to figure that out the past month or two

 

check your fuel pressure at the rails. Also, I wouldn't drive your truck again until you get this solved. My truck died in the middle of the road...not good.

 

yea its parked so Im driving the race car...or the 93 celica, whatever you wanna call it

 

I dont have a fuel pressure guage...if I can get ahold of one, what should it be at?

 

bump! any more ideas?

 

you can get them from any auto parts store, its about $20 i think and you just hook it up to the schrader (sp?) valve on the fuel raills should be around 58psi at idle i believe
