So basically this is my last attempt. I love my car, Ive done everything to it, but Im about to head to grad school, and need a it to be reliable. Problem is, I dont have any money to get a new car, and probably not enough money to get it fixed. I am at the point where if I dont have my car any longer, Im in serious trouble, and I would love to keep im 6th gen. Heres the story, My car is a 94 gt 2.2. I blew the engine around christmas, and put a jdm engine in. Same exact engine, but emmisions were different. I switched everything over. Since then the car has been idling incorrectly. At first it idled too high, then the rpms would jump up and down. Ive tried everything.Looked for vaccume leaks, checked timing, idle air control valve, map sensor....everything you can imagine. Now my car is stalling all the time, rpms are up and down, it bucks, and runs like ****. Ive done the clutch, engine, struts, tires. Ive worked on this car harder than anything else in my life. Ive taken it to two shops and they were stumped. If there is anyone out there in or around massachusetts that is an absolute guru and loves to work on 6gc's that wouldnt mind helping me out, id be extremely grateful. Again this is an absolute last resort, because I know i am asking a lot. But i really need some help and figured the 6gc community might be able to lend a hand. Thanks guys, I appreciate it.

Ive checked the vaccume lines by spraying it with carb cleaner. ive checked everywhere. Occasionally there is a slight change in idle from spraying, but nothing considerable. Chaos, thank you very much. I appreciate that. Taking out a student loan to get it fixed was actually my first though. unfortunately, not only will they not let me take it out durring the summer, but im limited to the amount i can take out. im pretty much tapped once school is payed for.

also pressure2, it is definately a 5sfe, I ran into this dillema in the past. You can check my old posts. its 100% a 5sfe. Where it came from is definately questionable though

Manny should be able to help you xD

You had a 5S and you're sure you replaced it with another 5S? I thought the JDM and USDM engines had the same emissions, only the Cali spec were different.

Possible ECU error?

Theres no engine code showing. For some reason when i pull the map sensor, the engine revs up, but runs better. So ive been running the car without the map plugged in for the last few weeks. that is the only time the light comes on.
