I recently got this car running again after several years in storage. Due to illness, I had farmed this job out to a local smog shop. "Make the it pass smog and bill me" was my directions. After 3 months in their shop, I took it away from them. I would only pay them for parts because they solved nothing. Still feeling poorly, I sent it to a second shop. No help whatsoever. I have now recovered from my health issues. Working on it myself. Using a Bosch 1350 scan tool, I found the Manifold Pressure Sensor to be defective. Replaced that and cleared it's codes. How can I be sure the problem is solved ? I only have my Bosch tool to work with. I have run it several times with no indication of a problem. Bear with me. I am a bit "old school", but any imput would be appreciated. ...Jim
Not sure what the other guys issues were. This seems too easy. I DID find a EGR air flow code [M0400] in there, but they had cleaned the EGR port out and replaced the EGR before I got it back. I cannot put it on the road because it is no longer licensed. In the shop, it seems fine. I am a bit rusty at this sort of work. Just trying to be careful to get it right before I pay all the fees to get it legal again. ...Jim
This was the "job from hell". It has been sitting around just over 2 years now. It went all sour on me on a trip up to my mountain cabin. All of the sudden went all rich and smelled like fuel. By the time I got it home all the O2 sensors were toast. My diagnostics program in my laptop died before I could really get started on it. I farmed it out while I got very sick. So a lot of what I know is second had . When I got it back it was still running sick, but better. Fuel trims jumping all over the place.Tested the MPS with a meter on a hunch. It failed. Car back in storage for another year. With the lock down for the virus, I have nothing but time on my hands.
Bought a new scan tool and went to it last week. ...Jim
The only way to confirm it will pass inspection is to get it to run the internal monitors, and it won't do that until go through the drive cycles.
Kind of a catch 22. You don't want to register it until you know it will pass but you won't know if it will pass until it's registered.
Can't drive it without smogging it first. Can' t smog it without driving it. DMV gives you a ONE DAY "moving permit" and only ONCE per vehicle, and they record the mileage on thier computer system. Annoying ! ...J.D.
