I added restore to my 2002 CRV when the engine was cold, ran it for about a minute and shut it down. Next morning the car stalled after going 1 block. Got it towed to the Honda dealer. It coded out as a variable valve timing sensor problem. The tech rapped the sensor with a screwdriver handle and the car ran ok, but still coded out when driven. The replacement cost including software upgrade was to be over $300. The car ran ok with the check engine light on so I drove it home since the part had to be ordered. After 15 miles of driving the code light went out and stayed out. I'm out $50. Cancelled part order. Be advised.
