Rich Condition??
I believe that I have a rich running condition. The car is a 87 3.2 Carrera. If cold, and you try to say, back out of the garage it will die. You can get it accomplished if you give it alot of gas. If you let it idle for a minute you will not have this problem. This causes another issue. If you let it idle you get fumes from the exhaust that are hard on the throat. Kind of smells like gas. General driveability is good, I just think it should have more power, and gas mileage is terrible. There is no stalling or backfires, other than what is listed above.
I don't have any guages or meters to run diagnostics with, so I plan just to start replacing parts. The car is 100% stock and the PO did just routine maint. Any ideas where I should start first? Thanks, 337 |

take it to a shop equipped with a gas analyzer and get the mixture properly checked and adjusted, preferably one familiar with porsche and with the 3 mm hex tool needed for the adjustment at the fuel distributor..end the guessing game over your mixture condition, then you will have a solid baseline on this parameter for future troubleshooting. if you aren't much of a diy type, get the basic idle and timing set too. your car will thank you for it.
 good luck!ryan

What about the Head temp sensor and the DME relay? Do you think either one of these could be causing this condition?

O2 sensor (bad or disconnected) will run rich.
A bad DME relay won't cause rich condition but it usually will affect idle. I'm not sure about Head temp sensor. Check to see if the WUR will affect it.

I didn't know that 3.2 liter motronic engines had fuel distributors or 3mm allen screw adjusters.
Just playing with ya Ryan  Take the car to a shop and have it checked, or get an exhaust gas analyzer. You can also do the shotgun approach, just start changing parts until eventually you find out what's wrong, but that can get really expensive and wasteful. |
