hey id appreciate it if anybody's got some insight on this...and can help me out

i had intake, exaust, downpipe and midpipe on my fd...and obviously i was runnin lean...and it was gonna take a while 4 me gather the cash 4 a power fc... so i drove my car for bout 6 months always at low rpm (shiftin by 4500... 5000 max) .. i know, that's not smart

but anyways..now that i got my power fc, got the fuel mixture adjusted...car runs much more powerful.. but it "hesitates" or meets resistance whenever it goes over 5500 rpm...u can feel it both when pushing it slowly...and w/ WOT. it WILL go...i can redline it.. but i can FEEL resistance (no it's not knocking, cuz the power fc shows it's not runnin lean). its almost like the engine's strugglin.

one of my friends was tellin me it's prob just carbon buildup.. and it should slowly go away the more i push it...kinda like breakin in my engine for higher rpms..

anyone ever heard of somethin like that be4?

thanx

It could be that you need new Spark Plugs, Wires or better Grounding. These are all easy things to fix/upgrade. Do the Home depot grounding strap mod. It's cheap and seems to help.

If that isn't the issue you could buy and HKS Twin Power Ignition Amp. I had hesitation at >5500 rpm after I installed a Supra Fuel Pump. I don't know if the car ran too rich or not, I just know that I got hesitation. So I installed the HKS Twin Power and my hesitation issues are history... The car feels like it has more low end torque as well.

Hope this helps.

actually.. i plan on changin my spark plugs & wires this weekend..

as for the grounding upgrade.. yea pettit racing sent me a free one a while back..the "chassis & engine ground update kit" (they do that whenever u 1st order from them).. so i guess ill go ahead and do that as well.

hopefully it works.
thanx man

i dunno if this makes a diff...but it's not a single spot where it hesitates, like the cold start 3000 rpm hesitation.

i mean a hesitation or resistance starting at about 5500 - 6000 rpm.. and it CONTINUES throughout the powerband..to redline.

im going to go with fouled plugs. if you always babied it then carbon build up on the plugs are more in likely the culprit. did you happen to remove the 4 wires in the harness prior to installing the PFC.
talk to me on AOL IM. i use the same name as i do here.
