Alright I bought 2 240's one is a 92 and the other is a 94. The 92 had no engine, but the 94 did, so I put the engine into the 92, the engine is all stock. Eventually got it running sort of... The car will idle just fine with the maf unplugged, but once I plug it in the car dies. It will stay running if I give it some gas. I've bought a new maf and nothing changed. I've replaced the fuel filter, checked the fuel pump, it was good, replaced plugs, wires, cap and rotor, I've removed the IACV and cleaned it, I've checked all vacuum leaks and all seemed to be good, I've replaced the TPS, and I think that's it.
I've seen many people on the forums saying they are having similar issues, but no one ever posts what the end problem was. Hopefully I can be specific enough to try and hunt this haunting ka motor issue.
All help and ideas is appreciated.
