What are the symptoms of valves springs going bad? Same with a fuel pump? I think the pump isgoing to crap, just want some info. Please Help

 

what is the car doing? does it seem like it starving for fuel or not running good or what, could be other things. the springs could go bad or get weak and break and if there weak they could not seat the valves right.

 

Hesitating sometimes. When i am crusing sometimes it starts to studder, like it's not getting fuel, but i gun it it goes away. This happens some times from a dead stop take off gunning it and in 2nd about 2900 rmp it starts to studder. I let off the gas let it " Catch up" , and it's good to gun again.

 

could be fuel pump, thats weird

 

Fuel Injected or Carb?

 

FI , I have replaced the fuel filter, IAC, TPS, Cleaned air filter, and cleaned throttle body. I have in the car Ford Racing Blue Wires, Flowmaster mufflers, off-road H-pipe. Stock air box with a K&N filter. No AC, no smog. New clutch and cooling fan. Shorty headers, 30# injectors and 76mm MAF.
