What the hell was that for? I explained what the noise was as you had no clue! And checking resistance on a sensor is a good thing in my mind not a bad one. Takes a few seconds to check and then verifies that it is ok if it is within the proper value. For your information if the crank position sensor is bad the plugs will still fire until the engine actually starts, so if it is bad then the Ignition Module never knows when the engine runs so therefore as soon as the key is let go it kills spark! Easy to check, you unplug and check. Why load the throttle body up with carb cleaner if it is not needed. Since the more carb cleaner you stuff in there the less likely it is to run. Have you ever sprayed carb cleaner directly into a running engine's intake? They stall when there is too much. A better idea would have been ether! I have a can just for that purpose as I needed it when I was done with my head gasket and all since the mixture was so lean the engine would not start. Once started though it would run rough enough and stay running long enough to set the mixture properly. Couple sprays was all it took. As for the rubber boot, thanks for not believeing this can cause a problem. Look at the actuall 190E forum and check it out, it happens more often than you would think. And a simple test is a heck of a lot better than spraying carb cleaner for no reason what so ever. ***** a visual inspection will tell you more than that. And as an FYI I personally had a bad Water Temp Sensor and bad intake boot cause issues! They were both bad when I got the car, and I have sprayed many a can of carb cleaner in the intake to clean to no avail. So sorry if I don't quite think Carb Cleaner is god's gift to making an engine run. A loaded up intake would not stop the engine from ever running. But a massive air leak, or bad sensor would. The Water Temp Sensor tells the CIS-E what the engine temp is, to fire the cold start valve and actuate the IACV as well as lean or enrichen mixture via the EHA. Well if the sensor is telling the CIS-E that the engine is running at 120 degrees then it will lean the crap out of the mixture and the car will not start. Also if the base mixture is too lean it will not start. If the Crank Sensor is not good it will not start and run. ***** if the OVP is bad and it is cold out it will not start without help! So easy things to check are better than going out and dumping more money into it for Carb Cleaner, even though it is cheap!
