2000 E350 7.3 Chugging...Help!!!
I posted this in transmission problems a few weeks ago but didn't get anywhere with it. I'm still trying to figure it out so here it is again.
It doesn't do it all the time but it seems that when I drive down the road with the cruise on at 75 my van runs great. However, when I drop down to around 65 or lower and my van is still in OD I get a shudder, sometimes bad. As soon as I hit the accelerator it stops. It almost seems like the OD is too high for the speed that I am going and the van is trying to catch up with itself or something...If that makes sense.
I have a superchips high performance programmer and code reader installed as well just in case that would matter....
Previous owner installed a rebuilt transmission in 04 with a "tugger" kit (I'm really not sure what that is). And had the injectors all replaced last year...He really kept up on the maintenance.
So I hooked up the Superchips tuner and read the codes.
I am getting a
P0238 (Turbo Boost Sensor A Circuit High Input)
P1670 (EF Feedback Signal Not Detected)
Both of which I don't know how to interpret.
P0460 (Fuel Tank Level Indicator Circuit Error) Thanks to the transflow, but I worked this one out.
But nothing that points to what the problem is with the chugging I am getting in OD.
I also pulled out a receipt stating that the PO had all new injectors installed on June 13, 2007 at a cost of $2006.00.
Does anybody out there have an idea on what the problem might be? Also, how can I test the injectors to see if they are bad without pulling them and without getting a code?
Also, it shutters a bit on take off and when I accelerate during normal operation. I've been reading something about a camshaft position sensor. Can this be the problem?
