Engine running poor after timing belt

[Woods247]

Could do a Relearn with the Cobb ap3* If you haven't already.

Yeah I did that first. I used it and ForScan to watch for misfires but none occur. It’s probably good. Probably.

Looks like I’ll be re-timing my car. Something is definitely incorrect even though I don’t see codes. Boost levels are normal but I was 10mph and 5 seconds a lap slower yesterday than I was on similar (weather) days over the last three years. It stalled after it cooled down when I was putting it back on the hauler too. It must be an issue with how the procedure was done. I can’t think of anything else..

Id try to insert the timing pin, flywheel lock and the cam bar tool to see if its all in time prior to yanking the belt and TTY bolts. Document that it is off prior to having JST retime the motor so there is no pushback.

As I suspected the timing is off. The logs from this morning on cold start showed VCT-I Angle pinning at -41 sometimes. It was definitely off. They’re putting it back together and I’ll pick it up next week.

That’s what we did.

Man.. After correcting it the tool doesn’t line up again after the engine is turned over twice. It’s like the belt is stretched a bit but I have no idea why that would happen.

just saying, you're not far off and the FSM says you may have to rotate the cams slightly to get the tool to fit:

It was a bad tensioner from Ford. Replaced it and alls good.

DOA tensioner? That is a total bummer. Everything good now?

 

[madhatter]

Yeah man. I had a DOA slave and now a DOA tensioner from Ford. Crazy.
