Hi again from Munich!
Here are the details. But please see update from Feb. 5th below! I have a D-Jetronic intake. Under load and at about 2800 RPM Im experiencing an intermittent hesitation. Yesterday my son and I took the car out for a drive from Munich, towards Innsbruck and back and we ran into a bit of rain coming along the Aachensee (lake), and this hesitation got worse. Then I remembered the only other time I've had this car out with 100% humidity and that it wasn't running well on that day either, so this is apparently a clue. So what can this be? And why does it happen at all, even when it's not raining, albeit not as noticeably? Is there a cure? Experts / senior gurus out there, thank you for your time and sharing your knowledge and experience, in advance! With kind regards, Mike in Munich (IMG:style_emoticons/default/smilie_flagge6.gif) |

Tested CHTS, <300 Ohms when warm. Approx. 2000 when cool. So that seems to be working OK.
Found one hose at the pass. side of the engine on the corner of the fan shroud which had come off. Capping it didn't seem to change the idle much at all, so not sure if that was the reason why the idle had gone up so high or not. Waiting for TPS rebuild kit from Dave Sprinkle, which will be installed next week. I'm hopeful that this will solve the issue. Will report. |
