So I when I bought my 92 gt from the original owner it ran like a dream, almost perfect. I installed a moroso intake, bbk headers, bbk o/r H pipe, mac catback, and march underdrive pullies.
One day I got in the car and it did not seem to rev as easy or idle as good anymore so I ignired it saying it was in my hard. The gas milage dropped from 240 miles per tank, down to 180. Now the more i drive it, it seems to be hesistant under light throttle and you have to give it more gas to move than before, it kind of bucks like it would when you let off the gas and coast without pushing the clutch in, but nowhere near as noticable, its real light. It also sounds like it has a baby cam in it at idle, but i figured thats just can you can actually hear it run now lol.
At fuel throttle the car seems to be ok though but still seems like it takes way too long to rev. The fuel pressure is at 42psi with no vacuum on a stock regulator and the timing is at 14 degrees.
Things I replaced before this started were:
-msd wires
-msd cap and rotor
-autolite plugs
-Fuel filter
-pcv valve
-MSD street heat coil
-ran seafoam through
-New o2 sensors
One thing I noticed was that the fuel pump is really loud but it reads high pressure and even after sitting all night barely primes in the morning I guess because the pump is holding pressure?
The check engine light is not on......Can someone lead me in the next direction? Thanks so much.
