I was driving on the highway today, and when I turned onto the exit ramp and put the car in neutral I noticed my gear shifter shaking back and forth pretty violently. I looked down at the tachometer and saw it idling at less than 200 rpm’s in neutral. I got to the light and my car stalled. I turned it back on and I had to feather the gas pedal just to keep the car running. I was able to make it to my local car mechanic with one foot on the gas pedal and my hand on the e-brake. It runs a little rough when in gear but at least it keeps the rpm’s up enough to stay running. The check engine light never came on. My guy said that he didn’t have the appropriate diagnostic machine, but he’s afraid I might need a new throttle body and a new computer which may cost 1000’s of dollars. I think the code he told me that he found was P0506. He sent me to a guy that deals only with Japanese cars, but they won’t be able to look at my car until Monday.
Any thoughts? Hopefully something that doesn’t cost 1000’s of dollars. And if I replace the throttle body does that mean I have to replace the computer too? Is there something that I did or that I didn’t do that I should have been doing that could have caused this to break?
This is going to be a long weekend,
