hey i just installed a vafc 2 and a n autometer A/f gauge recently and i just wanted to go for a nice drive, and punch it in second/third gear... well I DID and at 6600 rpms the car just (100 throttle) the car pretty much just stopped goin.... it was Weird as **** but im pretty sure it wasn't a detenation ( sp) becase iwa swatching my a/f guage and it was just on Rich as always( when full)....


after i just coasted, put it in 5th then just drove... after i had to stop, and it was driving PERFECTLY.... what was the problem

anyone know?

sparkplug problem?

 

You may have an installation error as the ECU is in protection mode which limits revs to 6500rpm.

 

hmm that could be it then... any specific wires that would do that?

 

di you hit fuel cutoff, or did the engine just bog a lil and then tae off again? if it was the later then remove some fuel @ 6500 rpms via the vafc

 

questtion.. is it exactly at 6500 rpms?

im not sure if its good that i drive that hhigh until li get this situated


if it goes to like 6600 on my VAFC... whats up!

foul spark plugs?

its been drviing perfectlly so thats whay i think its my ecu.. is there any way to diagnose this problem.. specificially... ex: The pressure signal in my ecu, is not connected" or something of that means.. or do i have to go into my ecu and check my 20 connections or so?

 

was the engine warmed up?

 

i dunno if you've read this, but this covers pretty much everything

it was warmed up i guess... drove for about 3 mins be4
...

and the vtec worked it just stoppped (fuel cut) at lkie 6600 rpm i think

 

do you have any check engine lights???

 

Fuel Filter?

 

fuel filter would not cause it to bog to **** at 6K then be fine at low RPMs. Do you have any Check Engine Lights? (CEL's)

Check your oil level also.

 

no cel's, im doin an oil change tmw..


should i drive it to redline to see if it does it again?


i think it might be the ECU protectionthing, but i woul dhave a cel i think...

I HAVE NONE


maybe its my sparkplugs?

 

DELTE THIS WHOLE THREAD PLEASE


check my other one


sorry

 

Shrug...a clogged fuel filter can cause lag due to that the amount of fuel required to go through the filter is stopped by the gunk inside.
