EDIT:
was just too much fuel injector cleaner in the tank messing with the tune, once i ran though that tank, running normal again!

alright so my car is a 05 MR. its running on E85, basically the mods are bolt ons, fuel pump, 1000cc injectors.
so yesterday i drove my car to lunch, and then to get beer later in the day, probably around 6pm. car ran fine, everything was good. been sitting at my buddies since that time, untill today when i get into it and start it up to come home, i let it idle to warm up, everything seems normal for like the first 20 seconds its running, then all of a sudden it starts running terrible, so bad that the entire car is shaking. giving it a little gas made it want to die, and makes it sound even worse. it sounded like it was running on 3 cylinders or something. i was only going from my buddies house to my house (about a 3 mile drive) so i limped it home, by the time i got into my garage to further investigate, the misfire was gone and it seemed to be running normal again. wtf?
a few random facts:
its pretty cold right now when this just happened (46 degrees)
i filled up with a full tank of E85 yesterday on the way to my buddies, and put in Lucas fuel system cleaner for the first time since switching to E85.
i have never had any issues like this since the E85 tune.
any ideas?

I had an issue recently and thought it could be a number of things turbo, motor, etc... wound up being a cam sensor... You just never know
It isnt your timing belt, if there was something wrong with the timing belt you would have catastrophic damage more than likely and it wouldnt even run from bending valves smashing pistons etc...
I agree with the other post to check all your connections to see if it was something that just came loose.

so i started the car up again, idled fine for about 5 minutes, gave it a couple of revs up to 3k RPM and everything was fine, then it started running like crap again like its on 3 cylinders!! this sucks
I do agree to check the timing belt. Although i do agree with 06MRV8KILLER, a snapped timing belt causes catastrophic damages. Most of the time a bad timing belt will be picked up by crank/cam sensors and wont even let the car turn on.However, a loose timing belt with a lot of miles can still contribute to the problem. I know so because this has happened to me (on pump) Car would idle and backfire quite a bit, like it was running on dirty gas. Since you have never changed the belt, how many miles are on the motor? Checking the timing is not too difficult to do.
Also, OP have you checked the basics? Have you checked the plugs, coils, and wires?
