I have noted this weird intermittent startup "problem" on both my 90
Camry (2VZ-FE) and now my 2001 Highlander (1MZ-FE) and was wondering
if anyone has an explanation. It took me a long time to figure out how
to reproduce the problem. Here is what caused the most recent
occurance.

This past Saturday afternoon (3:00P.M.)  I parked in the driveway so
that I could wash the car. After hearing the forecast for potential
rain overnite I moved the car into the garage (7:00P.M). On Sunday
morning I pulled the car back out of the garage to wax it. The car sat
there until time to go to work on Monday morning. Everything seemed
fine to this point.

On Monday morning when I started the car it sounded like the engine
was going to jump out of the hood! It was shaking badly and I could
hear all kinds of ticking noises from what I hope were just the fuel
injectors. After a few minutes the shaking and missing calmed down and
I drove to work without incident.

Can anybody explain what is going on here? It would appear that 2
engine starts without a complete warmup somehow causes the computer to
forget how to properly control the engine.

Anyone have any other ideas or an explanation? This eeems like it
would be an EPA issue.

Thanks,

Steve
