Ive reset the ECU a few times trying to set the timing back. But will still run the same. And I've replaced the TBI gasket and manifold gasket and sprayed them down and still nothing. And the only codes Ive been throwing is the "Lean" code. Usally comes on after ive been driving. park it for about 20 minutes and start it up again it comes on and goes off after I start to drive.
