NEED HELP: car spudders

[MPF_Supra]

i tryed searching and it isn't helping.
Yesterday i was driving home from work, all of the sudden my car started to spudder. I was like wtf, so i thought maybe it needed a tune up, changed plugs and wires, and it still did it. early in the morning when it's cold, if you start it up, it'll idle fine for the first ten seconds than it'll run rough like it's missing. If you sit at a light it'll run rough as well. Otherwise the car was running like a champ a few days ago. any advice of guys who's been threw this would help. thanks

i have the same problem. mine will also do it if i am in gear and not pressing the gas just kinda going in gear. I think it a misfire problem as well. I started my car and the poping seems to be from cylinder 4 5 or 6 but not sure. My timing is advanced, thats the only way we could get it to run right. So any help for us????

I was gonna say that it is most likely timing. For a good while, my car sounded a lot like a helicopter it missed so bad. I fixed a BAD COIL as per the TSRM, but it still had a miss after that. Once I finally got a timing light, and set timing as per TSRM, it finally cleared up. It's starting to sputter a little again, so I will be checking that my timing is still good this weekend. My problem could be due to not having a good tune on my Lex/550 combo.

ya i checked my plugs the other day and they look fine nothing out of the ordinary. As with the injector clips i am working on getting a new harness because just like a few other clips they dont click on they fit on but there broken in spots and not full clips so i am thinking that is probably a big factor in my car sputtering. That and i have one wire pulled out of afm and two out of the ics or isc cant recall what the book said it was. I will prob be picking up a brand new harness from the dealer for 480 so its not to bad to know all the wires are right.
