Bent valve and/or other stuff like wires, injectors rings??? Give meeh some feedback.
// this is a follow up on a 3/2/03 post, engine at the track, dint redline but maybe caught meeh when i wasnt paying attention cuz missed going into 4th. rough idle to having to start the ignition again.. had to mess with idle not die. Also low compression in suspected cylinder 3, where its 100 compression which is half of the other ones.

 

ummm can someone translate what he just said?

anyways

 

What happened? What are your mods?

Code 45 is "System too lean or too rich malfunction in the fuel monitoring systems."

Code 73 is "Cylinder 3 Misfire or a Random Misfire a condition is present that is creating a cylinder misfire."


Sounds like a bent valve, but since your car is not dying, it's probly a minor bend. Should get that checked right away.

I often get a Code 45 myself, but that's probly me running to Rich with the VAFC and Cams...
