tried a lot of stuff now but need a hand here,
470cc blue inj.
Car starts up fine, no problem
When at idle it gives some puffs every now and then. Not a smooth steady idle. You can see this in the logs. Rpm, TB valve and MAP are bouncing a bit up and down.
When I slowly push the throttle it seems to go well, but with a slight puff/hesitation now and then.
When I push the throttle fast it bogs badly like its chocking and tends to stall. It never stalls cause it can get up pace fast enough once let go off the throttle.
When this bogging happens the car is smoking and tyhe spark plugs came out black within just 5 minutes of running the engine.
Other then that all is well. Car drives good.
Things I did:
Cleaned coil pack
Changed spark plugs back to OEM
Sprayed all connectors
Checked spark plugs -> Looked good.
Other things I read are:
Intake leak. Tested this and seems fine, but not 100% sure since its shitty to do yourself..)
Leaky injector (how to check?)
Thanx for input guys!
