My R is in pain. She is constantly stuttering. I have no check engine lights or codes. The idle is not smooth. She drops down to as low as 500 Rpm and back to 700rpm. She feels like she is gonna stall. I'm away giving her gas to stay on and the motor still shakes like a blender while she is in higher rpm up to 3K. I smell my exhaust gas and it looks like she is running very rich. I even tried to lean her out but to no avail. She leave a black stain on my rear bumper from all the exhaust fumes. I recently changed the fuel filter. I checked my spark plugs and they were black. Could this be the problem? New spark plugs needed?

Currently I have I/H/E, Fuel pressure regulator set at 40 Psi & Fuel gauge, aem cam gears set at +2, -1, stock ITR cams, Advance timing @ 18 degrees
and Field Vtec controller.

 

Did you overrev? That'd be my first bet.

There is a strong possibility that I reached 9200Rpm by accident. I have stock valvetrain and Skunk2 program which redlines at 9500Rpm. I know itr valvetrain can handle up to 9k safely. But what do you think?

 

check vacuum lines....

 

zero everything out(set everything back to stock specs, unplug your VTEC controller), and re-set the ECU... see if anything changes...

low idle usually means you have some sort of vacuum leaks, check all th evacuum lines, evap, map sensor and etc...
I have a turbo, last time it happened, my FMU was crapped, it stays open at idle, causing it to idle so low and run very rich....
I am just making an example of it...
also, check out your wires or distributor, it is very unlikely, otherwise you have threw a code of misfires, but check them anyway..

once everything is checked, reset ECU and see what happens...

You described my car a year ago. I bet it's your afc. I had a v-afc that screwed up my MAP signal (the v-afc it turns out was defective). It would take the car a few days to a week to finally throw a map sensor or a misfire code and go into limp mode, but those couple days sucked and the car ran real rough. Take off your afc and see what happens. A couple of ITR's have had problems like this with their afc's. Our ECU's are very picky when it comes to reading the MAP signal.

 

The problem is the skunk ecu is way too rich for your application. You need to lean it out big time with the fields. has nothing to do with overrreving

 

AGree with Jeff but also try this. Undo the plugs for the fuel controller on the Fields, I had this problem in my GSR and couldn't figure it out but there was something wrong internally in my fields that would cause it to stall when the fuel settings where hooked up. I unhooked the fuel controller part of the fields and it worked fine.
