Please help. I have a 94 Ls. The car starts(sometimes at rich idle and flutters up and down), but when I hit the gas it immediately stalls out. I've replaced the fuel pump and filter. The air filter is fine. I also replaced the MAF sensor, and cleaned the throttle body. Also, is it required to disconnect the battery after replacing the MAF sensor? Could it also be the crank sensor or Tps? Hellllp I don't want to get rid of her. Only 146,000 miles

I order an IAC from ebay for 55 bucks, along with a tps sensor. Throttle body recently replaced too along with plugs wires and all coil packs. Do i need a gasket for this IAC because it sure looks like it. I've never had to change one of these on a car before. Thanks again

Check your spark plug wires again, if you have replaced your oem wires with ****ty Denso wires. The insulation and heat resistance on aftermarket wires is not as good as OEM Yazaki wires.
Specially check for pinched spark plug wires close to the coils. OEM wires are not cheap but it can last for 30 more years. I had the same problem after wasting 400$ on parts that I didn't need, I found out the culprit was tiny stripped insulation on drive side coil wire.
Help 94 ls 400- erratic idle, stalling...
