Hi guys, my Cobra is acting weird at wot. She's falling on her face and down on power.
When i hit the throttle at first i got full power at 13-14 psi of boost till about 3000 rpm and a good AFR at 11.5. Then passing that point the boost keep rising 15-16-17 psi almost(wich is unusual) and fall on is face like if the belt is slipping or a Vac leak. Look like at that point the afr seems to go leaner as the motor is revving higher, and No Power.
So to be clearer ,- low rpm = normal boost = good afr ,good power.
- 3k-6k rpm = boost continue to rise(WTF??) seem to
become leaner, and unable to produce more power
Already done to the - new plugs Tr6 .32 gap
car
- clean the MAF
- new fuel filter
The problem is still there. Any idea guys???
sorry for the spelling
