4.56 gears in the differential... just replaced the fuel injectors and spark plugs. wires are good too. Coil is good as well. Even the MSD StreetFire coil made no difference.
MAF is clean. No vacuum leaks, i tested the manifold vacuum. it was higher than i thought it'd be and i'm okay with that... i think. At around 25" .
Fuel pressure regulator is good. fuel pump primes, maybe i should see if it holds good pressure under load.
So 1st gear does well but not enough power spin the wheels any time i want. Like i'll floor it, it'll barely go, then at about, idunno, 3500rpm it will spin the tires a tad bit. i guess it's an intermittent power loss here.
2nd gear i've heard you could move from a dead stop with this gear in 2nd. With whatever problem is going on i would have to floor it and the car would be bucking like a bull the whole time from a dead stop.
I have slightly spun tires in this gear switching from 1st in the middle of first gear but it does it when it wants to.
3rd gear? takes me too long to get there. I might as well be using 2.73 .
I've only made a pull to 69mph.
So what could be the problem ?
