help! it starts ok initially, then as soon as it warms up it'll croak! then it won't start again for maybe 30 minutes-1 hour then will start again just fine. it seems to have power coming out of the battery. read some of the other posts, - no lights on the dash coming on for the DAS, seems to have pressure on the shraeder valve thing under the motor cover. runs rough at idle. getting progressively worse. stuck me out for 3 hours the other day.sound like spark plugs or the crank position sensor? spark plugs seem a little oily around them, or at least 2 of them. no leaks detected in garage. 140k miles. horrible gas smell upon starting up.
