acceleration problem
My 99 V6 mustang is running bad. Going down the road (crusin) the car drives ok. But, when you give it some extra gas it acts like it is running out of gas. When the car warms up completely, the car has hesitation above 2000 rpm. The car has 88,000 miles and it's all stock. I have just replaced PCV valve, cleaned fuel injection system, cleaned trottle body, new sparkplugs, new wires, air filter, and run a code machine with NO results. NO CODES FOUND. PLEASE HELP. I DRIVE THE CAR 60 MILES A DAY TO WORK. Also, MPG was 25 now 19. PLEASE HELP.
THANKS

RE: acceleration problem
That wasn't aimed at you. Just a little sarcasm for someone else. Seriously, what did you use to clean the fuel system, did you replace the fuel filter before or after the fuel system cleaner, and have you cleaned your MAF?

RE: acceleration problem
2 other things I'd check. 1 fuel pressure. You'll need to either buy a meter, or take it to a shop. And 2 O2 sensors. You will again either have to buy a meter, or flash tuner, or take it to a shop.....

I use 3m fuel injection system cleaner with motorcraft injection cleaner liquid. Fuel filter was replace after cleaning.
