I was driving on my way to a town near my house this morning and I got to a intersection and my engine started hesitating and then cut out. I started it back up to move it out of the intersection and it worked fine for a moment and then the hesitation started back and no matter how much throttle I gave it, it would not go past 1k rpm. I'm thinking it has to do with my fuel pressure so I'm having someone run a fuel pressure gauge over to check it. any other troubleshooting ideas I should look out for?

 

would help to know the year and engine???

 

look at the thread you're in. sn95 4.6L out of a 2001 gt

 

haha sorry, its a 2001 gt with the 4.6L N/A only engine mod is a custom intake from AM and pistons and rods.

 

I had a 2003 4.6 and never had that issue but it could be a dirty throttle body air flow sensor or a loose wire to the throttle body. It may also be the computer. It could be so many things above and beyond what is mentioning and it is all a guessing game to some point. good luck and lets hope it is something minor and easy to fix.

 

My money is on fuel pressure.

Piston rod mods? Do elaborate please

 

+1 Fuel filter is probably clogged up

 

Turns out a grocery bag went under my wheel well and covered up my air filter. From it not responding at the throttle I pumped the gas pedal and the intake shaft popped off of my MAF sensor. Hence the cutting out.

 

Forged pistons bro.

 

curious as to why you would go to the trouble of going forged pistons and rods on a pretty much stock build motor when the factory hypereutectic pistons are more than adequate. just curious thats all.

 

No worries, just trying to give any and all variables.

 

 

Beautiful! :O
