Hey guys, I'm having problems with my motor and would appreciate some help. When I'm driving my car it's rides fine, but as soon as I get to 2k/ 2.5k rpm, the check engine light turns on, and then starts dumping fuel, my aem wideband starts to read 10.00. As soon as it does that I turn the car off and then turn it back on it goes away, but as soon as I get to 2k/2.5k rpm again it does the same thing. Do any of y'all think or know what it is, I would really appreciate your help, Thanks guys.

 

sounds like a tunning issue most likely. has it been tuned, are u using a basemap? are you monitoring fuel pressure?

 

Hey thanks for your response and yeah it's tune on a Hondata s300, and the light stays green on the ecu, and as for the fuel the only thing I notice was when I turn the key twice( not turning it on) the fuel pressure goes up, and then drops right back down in less then 5 sec. But when I turn it on it sits at 40 to 50psi at the fuel pressure gauge.
