Bought a celica off my friend a while back, it's the 1.8 VVTi
Whilst running with a cracked manifold, the car hit lift and performed perfectly (best thing I'd ever driven, LOvE IT!).
The Celica GT, VVT-i (1ZZ-FE) 1.8Liter 140hp does not have lift.
What is the CEL CODE that you are getting?https://www.celicahobby.com/forums/...light-diagnostic-trouble-code-chart.html
A simple and totally crazy but often overlooked "fix" for the common O2-sensor (also MAF related) CEL code tripping is a leak in your current gas cap washer. If your gas cap hasn't been replaced in 10 years and your Celica is parked outside often, this could be a simple $10 fix to many trouble-shooting head aches.
Again, I know it's a crazy suggestion, but it's often the typical one
What CEL CODE is your Celi throwing?
