4ag on the freeway

dae · 05-02-2004, 05:38 PM

dunno if anyone can diagnose this over the internet but here goes. when im driving my corolla on the freeway at about 70-80 the engine starts to kinda sputter and it seems like it has less power than before ( less power than a stock 4ag is a terrible thing ) I think i may have a cracked exhaust manifold or maybe a bad gasket there but im not sure if this is what might be causing it. any help is appreciated

im guessin maybe ur getting lean up there and maybe ur fuel pump/fuel filter....somethings failing in the fuel system

is it only at that speed or at high RPMs.....

mainly at steady high rpm. sounds like you could be right

fuel pump? my close buddy has replaced his fuel pump in the two years he's had it. another neighbor has replaced her fuel pump 3 times in the 19 years shes had hers. might want to have a look at that too.
