ok my car is still missing 4-5k i have done plugs, wires, cap, rotor, ignition module, coil, 02 sensors, removed egr, smog pump removed. ok yesterday i adjusted timing RETARTED IT and uped my fuel pressure to 32. i have 24lb injectors. and it ran fine now it runs like crap again i do not know what it is, i cant find anything wrong, im so stumped.

ekthrilla

your fuel pressure might be low. check it to make sure its still at 32. it sounds like its leaning out bad.

isnt stock fuel pressure supposed to be at 38? Also it could be time for new springs. You say you have reved it really high before.

razarr69

Yeah with the 19 #'s its 38-40 but since he has the 24# its lower.

Did you block off the ports in the back of the heads where egr and smog was hooked up? Whats you vacuum at idle. Should still be at least 18 unless you lobe seperation is real close.

Also my car seems to miss when it gets to 4k rpm and higher. But my problem is the rubber ring around my harmonic balancer is starting to back out and causing internal vibration at high rpms.

zach you may want to get that fixed, ok i may have it fixed the sensors on the back of the shock tower for the smog crap, i pluged them back in and it seams to run fine, my fuel pressure is 35 at idle i made it a little higher. i still have the pipe on the back of the heads i have bolts to put in the head but i never got to put them in this weekend, also when i took the egr off i made a block off plate. so as of right now it runs good, tomorrow is another day, thanks for the help

in plug your o2 harness,and see what happens...i had a burnt wire,and went through all what you have done.

Tims 88GT

yea i almost had that problem before, they started to melt but i got to them before they went through. but like i said so far i have it fixed.

grabbem88

you did your coil?

Tims 88GT

yea but that was not it, it was the dumb smog sensors
