Haven't pulled codes yet, but I've had two incidents where the power went to idle followed by Advancetrac, Hill Descent, and Sway Control warnings, all of which depend upon throttle control to do their jobs. Looks like the throttle plate is sticking, (TPS signal does not match what the throttle command requested) or the control motor is bad (electrical contact degradation appears to be an issue).

If the motor is fouled, I would like to replace with something that is better quality, and might as well get a better breathing TB for a few extra pounds of torque.

I invite commentary regarding experiences with after market throttle bodies for the first gen 3.5 TCDI as that is what inhabits my engine bay.

I am also interested in commentary on catch cans for this engine, as I'll install one while I'm replacing the TB. Some seem ridiculously expensive. Don't need a purty one, just one that does it's job.

While I'm in there, I think I'll pull the intake and check the center valves.

Time for Ford to get their **** together. Wife's 2013 Escape has had two TB replacements, and it's acting up again. They are throwing the same bad stepper motors at that problem, but are replacing the entire TB instead of just the motor. I can't imaging the money they are spending on that fiasco. Stop buying $4 motors, Ford.

Thanks!

 

Just get the BBK 65mm one or whatever, slightly larger, doesn't need a tune to work properly, should be fine.

 

Thanks! Does anyone have a part number for the BBK? I was looking at it online at a few sites, and they were ambiguous as to whether it was for the 3.5 eco or N/A. Might be the same for both, but I know not...

Also, isn't the 65mm for the 2.7? 73mm for the 3.5 eco?

 

This is the one I put in my 3.5 eco https://www.americantrucks.com/bbk-7...dy-1114v6.html

 

Can't help you T/B's, never replaced anything that small, but when I did upgrade one, it needed a tune.
Catch cans, ( air oil separators ), installed a Jegs unit on both GT500's & my 17 F150 5.0. Less than $ 50.00, spliced into the Ford OEM tubing, & it works.

So, four limp mode failures in less than two weeks with Hill Descent or Hill Assisr or Advacetrac failure warnings and See Manual with Service Wrench, but no PCM codes, just codes from other modules complaining about bad PCM data.

Last night I was prepared. When thr inevitable happened, I pulled off the road, left it running, and hooked up the laptop.

There she was, P2112, stuck throttle plate. Even though my hunch was correct, I was still relieved to see that code, having placed an order for a BBK 73mm throttle body.

Cheapest I found was AmericanTrucks.com, $429. Gave them my email, they sent a $15 off coupon. $414+tax.

OEM is $200, but no way to tell if I'd get an improved part, or part with the same early failure issues.
