Car running terrible, hesitation and running very rich
Hey guys I've got a 98 trans am that's been running terrible the last little bit. The car has about 200,000 miles on it so it's time for problems to start coming to light. Anyways lately it's been running very rich and barely runs at low rpms but picks up when you get on it and feels like the powers there. It black smokes bad and I pulled and cleaned the plugs so I know it's running rich. I replaced the iac valve, checked fuel pressure (58 to 60) psi, checked tps voltages and MAF voltages. All seemed in order. I also have no codes for o2's.
Mods include:
Kooks LTs and new exhaust
160 thermostat
Slp lid
AIR and EGR delete
Has E3 plugs and K&N filter
Any help would be much appreciated!!!
