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.
