a funny 3k hesitation...

1twistedrx7 · 03-19-2009, 08:56 AM

Ok my fd is having the 3k hesitation problem horribly but here is the kicker only after 50 degrees celsius. She will run great up until that point even at 49 degrees celsius but as soon as she hits 50 she starts acting up. I have a power fc w/commander thats how i know that its 50 degrees on the dot. every single time its not my pfc as i have tried another one and still the same problems. i have replaced the water temp sensor. checked adjusted and double checked my tps. The double throttle control and still the same problem. any help is greatly appreciated.

thanks

The 3k hesitation is really only suppose to effect the stock ECU. So your problem is different from the normal.

What exactly is it doin? What's the boost doing? It could be fuel cut in the PFC from overboosting. You really need to log it if thats possible.

Well when it happens its like the car wont boost... my wideband shows like 17 then then three dashes (aem uego) and when i watch my fuel injection duty on my commander the injectors doing their job but she just wont boost!!! how do get to the fuel cut? through logging?

It's may just be going lean when you step on the throttle, which is common with the PFC. Or it may just have a really lean cell that needs adjusting.

You should contact Chuck Westbrook(cewrx7r1) and get his notes and get in the PFC group, there are alot of people on there that know a good about about little problems.
