Anyone in San Diego familiar with Power FC and or TPS adjustments.
I’ve tried everything and I can’t get my FD to run properly. Started out with intermittently cutting out when driving, then occurred more frequently, now I cannot even pull it into my garage without it choking and cutting out when I hit the throttle.
almost seems fuel choked, but replaced the pump, spark plugs. PFC only reaches .9 and 2.10 under throttle before it chokes backfires and dies.
Not sure if there is a loose vacuum line failing under throttle, tps is off or what the issue is at this point.
It is not tuned due to discovering a blown turbo seal on the dyno for tune. 2ndry turbo is shut down currently and running non sequential as well.
Anynone?

 

How’s it going? Haven’t logged in awhile but I’m located in San Diego if you still need help.

 

appreciate it. Turns out the throttle body gasket had a chunk missing. Found it when I took it off to get to the TPS.

 

Any shops familiar with FDs around San Diego? For things like replacing the vacuum hoses?

 

Mazda has reissued sets of the vacuum hoses. I think there is maybe 19 at about US$30 each. But they are formed to fit, and so would make a DIY installation more intuitive. The key is to avoid breaking the solenoid nipples. Probably another US$600 to replace the solenoids as well.


I think Tom may have fixed his issues with a replacement TPS. He discusses in some other threads.

 

Thanks, still would love to know any shops that San Diegans trust to take their FDs to.
