89lxhatch

i have a 89 lx hatch 5.0, it is idling rough, i bought a new iac and installed it but when i plug it in the car idles worse and dies, and when i try to accelerate it sputters and falls on its face and then takes off, any ideas maybe the egr? When the IAC is plugged and i am driving it the acceleration problem is better, but the idle is screwed any ideas

verify tps is .99
no vacuum leaks
make sure o2 are good
maf is clean
or you can buy a code reader

perform the koeo and the koer test and then perform the idling reset

Check codes before you go throwing parts at it.

check codes,
check your grounds, one at computer, one at battory to wiring harness
fuel filter old?
bad gas, low tank?
