OK so my 10th ae has been giving me some issues and it is seeming to get worse... while driving down the road it acts like it just shuts off as soon as it does it i let off the throttle and it picks back up and seems to be fine then it will do it again... It builds boost fine doesn't break up or anything it is just at steed speeds.. What is causing this.. I have put a new o2 sensor in it about a month a half ago... I just don't understand what it is.. I have even adjusted the tps and tried riching it up a lil bit via safc... I need some help on what to do next... I have no clue where or what to do now.... Here is a list of mods done to it.....


-Koyo aluminum radiator
-SAFC II
-racing beat fcd
-all emissions and rats nest removed
-act 6 puck clutch
-light weight flywheel
-custom exhaust manifold
-2.5" down pipe
-2.5" high flow cat
-HKS front mount intercooler
-rfl dual horn bov
-k&n intake
-GReady PRofect A boost controller
-Tien fully adjustable Struts and springs

any info and help would be greatly apperciated....

 

someone has to have a idea what is wrong with my car anyone......

 

Is it anything like what's described in this thread? If so, we're still looking for a solution.

You're saying it will only do it at steady speeds? What if you hold your speed at 75mph, 80, 85? My light throttle hesitation will show up (87 TII) under 70mph in 5th gear, and if I have a tailwind it can do it at higher speeds. On my car, near as I can tell it may be that at low enough cruising speeds the car's pulling enough vacuum and such light load that the ECU thinks I'm decelerating and so it cuts fuel. I have noted with both a WB and NB O2 sensor that it leans out badly when this happens, and can be corrected by either letting off the throttle for a moment or applying a significant increase in throttle for a bit.

 

I read that whole thread and it really dosen't seem to match my problem all the way... Here is a lil more detail....

It doesn't do it all the time and the times I have found it to be is when it is hot out and the car is completely warmed up...

It doesn't break up it just loses all power at aboout 60mph and if i let of the gas pedal a lil bit it picks back up and goes fine for a lil bit then it will do it again...

It almost seems like all power is cut off then turned back on once i let off the gas...

It builds boost fine and dosen't break up or anything....

I was just wondering if it might be a temp sensor but not to sure.... I am totally lost here.....


anymore info would be great.....
