Lt. Dan Posted August 9, 2015 Report Share Posted August 9, 2015 Hey gang, I tried searching and couldn't find anybody that ran into the issue I'm having Tonight, I tackled a split intercooler coupler, and a failed harmonic dampener. Before the work, I had a check engine light, combined with a high idle. After replacing the intercooler couplers, I started the vehicle, and it idled fine. Replaced the harmonic dampener and installed a new belt. Now, the car will not hold an idle, and a quick drive around the block keeping the revs up shows that it's running VERY rich, with smoke coming out of the exhaust. Computer is not showing any codes. I have pulled the intercooler back off to check for any noticeable lines loose or any other evidence I damaged something. no such luck. What's my next step? Anybody run across something like this before? Link to comment Share on other sites More sharing options...

1975_mini Posted August 9, 2015 Report Share Posted August 9, 2015 I agree with nick, but you said you checked. So have you checked for stored codes even though you don't have a CEL at the moment. TPS could be the problem, if you disconnect it it should idle, simple check. I dicked up brandy's MAF sensor a while back installing a CAI. it would not hold an idle and if no signal is received it defaults to full rich, but not a rich as you are describing. unfortunately you likely have the most mechanical knowledge here. 1975 Mini 1000, 998cc A+ w/ K&N air filter, 10" Mamba wheels Link to comment Share on other sites More sharing options...
Lt. Dan Posted August 9, 2015 Author Report Share Posted August 9, 2015 UPDATE!! So, playing the whole "unplug and start" game, led me to the evap purge valve. When the vacuum lines are disconnected, the car will start, but run like it has a vacuum leak (because it does). I can then hook the vacuum lines up, and the car will run fine. Unfortunately, as soon as I shut the car off, I need to start the process all over again. Since I swapped the crank pulley and belt for new ones, I'm guessing I smacked the valve with the belt tool during the whole process.... Link to comment Share on other sites More sharing options...
1975_mini Posted August 10, 2015 Report Share Posted August 10, 2015 Glad to hear you isolated the problem. Hope that fixes it, do you have to order the part or is it one of those same part used on many cars and you can get it at the local parts store. At least you know how to start it, and its not your daily driver. It reminds me of when I was a poor 20 year old and could not afford a new starter solenoid until payday, I pop the hood and start my truck with a screw driver for like a week. 1975 Mini 1000, 998cc A+ w/ K&N air filter, 10" Mamba wheels Link to comment Share on other sites More sharing options...
