Trying to troubleshoot high RPM hesitation

[krazyazian]

Did a search to no avail!

I was playing around today with the Cobra making some hard 2nd/3rd gear pulls and it hesitates/sputters at high RPM like it's not firing on all cylinders. During normal driving it acts fine. Not throwing any codes either. Has anyone had this problem?

Thanks

Could be Spark blowout. What plugs and gap are you using?

SOmeone in checkers the other day was talking about something like this and he said he used the lucas fuel injector cleaner and it went back to normal.

I just had a case of spark blow out... it would missfire at high r's in third.. pulled the plugs out and regaped them to 34.. no problems now..

TR6's gapped @ .34

I'm gonna check the plugs this morning. I thought about the plugs but knowing my luck I'm sure it's something more than that.

Quick question. I noticed my intercooler reservoir fluid isn't circulating when I first start the car. Isn't it supposed to run constantly?

Thanks for the inputs everyone

Depends on the temp the tune is set to turn it on at. Does it kick on as it heats up?

[krazyazian]

It usually starts circulating soon as the motor is fired up. Not sure if RWTD did anything with it when they did my tune.

slightly off topic.. but what are your mods?

It's colder out now and there is a temp switch in the tune. Warm it up and see if it kicks on. If not don't go into WOT until you get it fixed.
