Hello all,
I'm stupmed. My renix 4.0 is running very funny. When it's cold I have around a half second delay in any gas pedal usage, and my idle bounces from 1k to almost stalling every second or two. If I give it a little gas, the rpms still bounce, just at a higher rpm(think leaving foot on the gas a bit) so its not just idle related. Here is a list of what I've done:
Checked:
Intake air temp
O2 sensor
Coolant temp
EGR and it's sensor
Replaced: (somewhat recently)
IAC
TPS
O2 sensor
Knock sensor
Fuel filter
So to recap, my idle bounces a lot when cold, and still does when warm, but a lot less. It has a delay in throttling up, more pronounced when cold. I also cleaned the throttle body about a year ago, so it had been a little bit but I wouldn't expect it to be gunked up yet. The engine runs well other than this, however it seems slower than it should be. Any suggestions? I will update this as I go , in hopes that this will be figured out.
Thanks
Francesco
