Question for the gurus..
Breif background on the car, d16z6 with greddy turbo kit, old school Hondata 2b , 440 RC injectors, 14 lbs. boost, 255 lph fuel pump, MSD SCI, MSD coil, Nology wires, stock engine.
The car has been running great for 5 years but lately has developed a problem. When the car hits about 3 psi, it studders like its on the rev limit but has no CEL. I took off the intake tube and with no boost, the car pulls fine to redline. I thought the map sensor took a dump, so I tried another with no luck. I know that the stock map sensor is at risk at anything above 11 psi, but has been running fine at 14. Also, the red light on the Hondata is solid red at idle, I have not had the chance to check to see if the light is blinking while the car is in boost, as I have been sick with the flu for the past few days. Any ideas would be appreciated. Thanks in advance....

 

im haveing the same prob. lets see if we could get some answers

 

anyone??

 

Maybe spark plugs fouled too much and you aren't getting some sort of miss fire while in boost? If nothing was changed since then that is the only thing I can think of at the moment.

 

I did put a fresh set of ngk zfr7-11 in the car after the problem started because the plugs that were in there were getting old, but alas, the car still has the same problem. When I feel a little better I'll check into this more, but in the meantime, does anyone else have any other ideas on where to begin looking? Thanks in advance.

 

May I suggest cap and rotor replacement. This is often a problem area that is overlooked. It doesn't cost much to replace. Also fuel filter. Let us know.

I normally start at routine maintainence items as alot of people overlook them and I do not know your maintainence.

 

Is the car running rich when this happens or leaning out?

 

Thanks for the replies... Basic cap, rotor, and fuel filter have been first on my list to change as they are a little old and in need of replacing anyways. I'll get to that as soon as I get the chance.

The cars a/f seems to be fine... I know because I have one of those fancy a/f guages and they are always right... haha!
When I get time I'll also look deeper into that Hondata box as I have had connection problems with the interface cable in the past. Thanks again

 

Problem solved!
Bad plug wires were the culprit
Thanks for the help!
