Under partial acceleration at random times my car will suddenly throw a CEL and completely lose the ability to accelerate. It will also buck.

The CEL will disappear the moment I lift off the throttle and the car will run fine. Even when I do give it over half throttle or so, 8/10 times it will accelerate smoothly and not give me any problems.

It seems to happen when the car is warmed up- ten or so minutes of driving- although it did happen once when I simply let the car idle to warm up (barely)

I haven't jumped the ECU as its freezing with friggin' gale force winds around here, but I would like some info in the mean time.

I do not know if it still throws the code at WOT- never tried. Gas mileage is normal, about 250-300 per tank.

Engine is a B16A block, GSR head and intake mani, GSR P72 with Hondata. Its only started happening within the last 2 days or so. Hondata has been installed for months with no problems besides an initial ELD code.

 

help

 

im leaning towards tps or map, check those suckas

 

Hopefully its the TPS - I have one from my old LS laying around.

if its the map......dang. Im off to check what codes I was getting.

 

I got off the phone with my tuning shop. They tell me since I have a Hondata, they can hook it up to their master system (hondata stage god-knows-what) and read all of the sensor voltage and engine parameters to tell me why my car is....well......******* up.

Lets hope its something cheap, he's leaning toward a TPS as well.
