Pinging/Pre Detonation/ NO CODES

Postby TITANG9 » Thu Apr 22, 2021 7:58 am

2014 VERSA S 1,6 (56,000 ODO)
NO codes :crazy: or anything unusual with Autel scanner (Maxisys Elite). :gotme :gotme
Coolant full.
Hard to start.
White smoke at start.
Lacks Power.
Engine pinging/ PRE detonation, after 1,500 RPMS during test drive.

All started after filling the tank up to the top.

Any ideas about this mystery?

White smoke on startup has to be fuel or coolant, which does it smell like? Same warm or cold?

Thanks, after not finding anything wrong using the scanner, we decided to empty the tank and use high octane gas. Problem solved...weird :gotme :gotme

Probably a stuck injector. Sea Foam would be a real good idea so it doesn't stick again.
