    same sort of problem it will sputter out when i go to lay on it it sputters and backfires sometimes, cleaned to air sensor and still does it, and if i'm on freeway and go to give it more gas it does that and also jumps a bit so i think that might be the tranny slippin, but anyone know why it sputters when i go to give it lots of gas

    SMOKEY, if your problem was occuring while driving I would say that it could be the fuel system. I would first check leads and spark plugs, some thing maybe failing here. Then I would check the idle control solenoid and make sure it is moving freely. Also check that the throttle plate is not gummed up. Another possability is a leaking injector. How is the fuel economy lately.....

    Toyo05 your problem sounds to be a fuel starvation problem or fouled spark plugs. Have you ever changed your fuel filter or plugs. Both good areas to start at...

    Did you check for engine trouble codes?

    Try this first. My truck did that and it helped. But now everthing has gone for s-hit, idles high, stalls, sputters etc. Pulled the codes and there is a problem with the the MAF at WOT, TPS is pooped and the HEGO(both) are running lean. Nothing but $$$ to fix. Bummer. I can pull your codes if you happen to be out this way. Might help you fix your problem.

    Mine sputters and almost stalls when I fire it up, then its fine. Just started doing it too, but haven't been able to mess with it though as I'm still trying to fix the rear brake line. I should throw a code reader on mine too...

    Hey Grumpyguy, I just very well may take you up on that offer (assuming I ever get around to changing that brake line ). The Sami is doing so well on fuel I've been driving it lately LOL

    What kind of plugs are you using? How do they look? Last year after I replaced my 4.0 I had some issues that ended up being a spark plug issue.

    At idle, it'd miss like crazy. When accelerating, it'd sputter/backfire. I knew the problem wasn't mechanical (good compression, etc), and a fuel pressure gauge led me to believe it wasn't a fuel delivery problem (although injector issues were still a possibility). My next test was to put a timing light on the plug wires and I could see a very definite miss across the board. As well, when watching the ignition timing, it would fluctuate by a good 10-15 degrees.

    I started thinking ECU issues after I ruled out air flow and crankshaft position sensors. Ultimately, as a last ditch effort, I replaced the plugs and the problem immediately went away.

    My plugs had been in my previous engine for only a couple of months -- which is why I didn't replace them with the engine swap. They were Bosch platinums which were rumoured around the internet not to work well with EDIS. The el-cheap champion plugs that I threw in to test are still in the truck -- without a hint of the problem since.

    -edit- Before replacing the plugs, I cleaned the MAF, replaced the IAC with a spare, replaced the CPS with a spare, replaced TPS with a spare, replaced the coil pack with a spare, replaced the fuel filter....and I had installed new plug wires with the engine swap. Nothing like taking the shotgun approach to fixing a problem.

    Your welcome to pop over any time. I've got a couple of brand new factory front brakelines if you need them. E-mail ( [email protected] ) me if you need to pull those codes.

    When it comes to plugs I have found that the plain jane Autolite's or something equivilent work the best and most reliably. It just doesn't seem worth the money to pay for the extra platinum or v-groove or whatever the gimmick is. If you run and MSD, Jacob or stronger coil then the plain jane's really show there strength.
