Just swapped out my multi-tech injectors for some j/y bosch ones rbob suggested.
Took it for a spin, and it got 2 gears and tryed for 3. It lays me back in the seat again. This is also on cheap OTC wires, and not giving the ecm time reprogram for the 24% increase in fuel I'm dumping in! No sputter at mid or upper range, just a cough down low.
The bosch injectors are so damn quiet, I wasnt sure my engine was running up front. No more clack clack clack clack!
YES!!! been fubar since 11-3-05

X, just cause it wasnt running right doesnt mean I wasnt driving it. Had to drive it to see if things fixed it.
Project, I know man. It was actually a combonation of several things. But mainly I did get debris in the fuel system as orignally thought. But I had other issues with spark, bad wiring, loose parts, etc.
Run to nashville again? You got me a convert?
I may be going to Indianaplis in june. But I gotta take the GTP for that.

Are you running the 3.4 injectors now, or are they still to big for that? If you're running bigger injectors than the 3.4 needs, you might want to watch out for a possible SES light for a RICH code. The O2 will try to pull fuel out, but it might reach it's limit and set a light, just a heads up.
Glad to hear that it's running better now though. Never like to hear about a sick thirdgen.

I had 19lb injectors in my 3.4 and it never threw a rich code.
I'm at 18.55 now. I think its still a bit much. Did fine on the way to work, so we shall see.
I see bosch makes some 18.1 and some 17lbs, may try to find them.

If the BLM are low (108, 110) then the injectors are a little too large. Part of the problem is that the injector flows are low (14# -17#), so even a 1 #/hr flow change is a large percentage.

I actually think the 15lbs and bump up my fuel pressure would be good.
Went to drive it this morning, its not fixed In fact, it was worse then it has ever been before.
Has something to do with it being cold out. I have no clue, and I'm totally lost.

If it's temperature related, chcek out the CTS and IAT sensors. Since you have the ability to data log, turn the ignition on and look at the 2 sensor readings. make sure that they are right around ambiant temp when the engine is cold and the start it and watch the temp rise, the CTS should rise evenly and the IAT should rise a little and then level off once the engine temp stabilizes.

The ECM does'nt know that you put 19# injectors in. When its cold the ECM stays in open loop and actually gives a rich command to pulse the injectors - but the duration "on" is based on the assumption of 15# injectors. So - you're running way too rich on cold startup. Does it smooth out once the engine is warm and in closed loop?

2.8. When this first happened, I pulled out the IAT/MAT and tested it. It tested fine, but I'm thinking about replacing it anyways. The CTS has appeared fine all times I've scanned it.
8492, I had 19lbs in it before and never had this problem before. I didnt have this problem yesterday to or from work. However, it may be true. It showed me I still have a miss in the engine though. So I need to find the miss. It was running so horrable that less then a mile from home I turned around and got the GTP. Its now sitting the yard with the nose up against the tree I ran into.
