|  1998 Mustang GT lags on acceleration
Whenever I hit the gas, and accelerate generally above 2000 RPMs it seems like the engine is either misfiring or not getting enough gas. It idles fine! I checked the MAF sensor, as well as the entire intake system. It has 120,000 on it and the injectors are all new. I think it might be the FPR. no troble codes are showing up. Any other ideas what it might be?
Thanks!

Actually yes, even so, the fuel filter was changed about 3 months ago. Thanks! | |
