Why is my F150 atalling under 1000 RPMs?

03 ford f150
Has duel exhaust leaks in manifolds

Yep

Hi so why should such a worn out old engine run at low speed simple reason engine wear.

  • Car won't accelerate, but rpms increase? I replace my alternator on Saturday and starting that same day my car has had problems accelerating. When I hit 10mph, the rpms shoot to 4000 and I have to ease off the gas pedal. Occasionally this is accompanied by a groaning noise. I made sure that the connections to the alternator were secure, but I'm not sure what the problem could be. The car is a 1997 Ford Taurus. I would really appreciate any advice.
  • Car consumes 3/4 Quart of Oil for first 1000 miles and basically stays at a 1/4 for another 4000 miles? I have been noticing this for sometime, no visible leaks underneath, no drips either and I have been looking and checking pretty routinely, what would cause after a oil change for the car to consume 3/4 of a quart for the first 1000 miles and then basically stay at a 1.4 for another 4000 miles? Vehicle is 2006 Ford Taurus SE OHV 3.0 note. When I say a quarter. I'm talking about the 1/4 line (amount) on the dipstick from full to re-fill
  • 88 ford ranger. Idling at 1200-1500 RPMs and gets 12 MPG. What is wrong? The only thing i have done to it was clean the intake with B12. I also used jb40 with that. Seems like sometime after that this happened. The truck runs great, its just idling high and its using alot of gas. Some trobleshooting tips would be cool. I don't want to go replacing a bunch of stuff i don't need too. I appreciate your help.
  • Why do my rpms go up and down while idling? I drive a 1997 ford Mustang v6, when I'm in idle the rpm guage goes up and down between 1 and the half mark. I know it's not just the guage because the engine clearly is review up and down with it. Should I take it in somewhere?
