Throttle on 240 DL 1988
Can anyone please help me. I am having problems in keeping the car running. It starts but then immediately stalls. Can keep it running if I disconnect the AMF. When I got to the throttle I noted that the flap was in the closed position. When I triede more gas I expected the flap to open. However it seemed to be in the closed position. Could push it a little in but nothing to speak of. It seems to be pumping gas but does not allow for more air to get into the throttle. Most seems to be going through the vent on the bottom of the throttle body. I presume that is a bypass to the cold start.
Any help would br really appreciated.
Thanks

The cable from the gas pedal is attached to the throttle via a clamp. When you pull the cable you can see the shaft and nut holding the clamp turning. Have the accordion section hooked back up so do not see inside the throttle body. But as I remember it the blade did not open when I did that before. It would seem that there was a disconect between the shaft on the outside of the throttle body and the blade. Not sure how that is possible. It is raining outside now so can not take the accordion section off as am scared that I may melt.

Thanks. I gather from that, that the rod somehow connects on one side to the cable assembly and on the other to the blade shaft. I had thought that the blade shaft extended ouside the body and then was connected to the cable assembly.
Could it be that the rod somehow got disconected on the blade side???

My appologies. Rain stopped so took off accordion section and checked the throttle body. The blade/flap does move along with the gas. Must be3 old age on my part as not thinking straight. Anyhow could not here the click from the throttle position sensor/switch. Took it off the throttle body. There are three electrical terminals on it. IF turn the center plug to one extreme get a zero ohm reading between term 1 and 2. If rotate the plug off the extreme get an open circuit between these terminals. The resistance reading between terminal 3 and 2 shows open circuit when reading between terminals 1 and 2 is zero. When you turn the center plug the resistance reading between terminals 2 and 3 seems to stay at open circuit until reach the other end end then seems to go to zero resistance. Is this normal????

Thanks. Not sure what the idle motor is. Have reset the throttle switch. Once again the car stalls as soon as I plug in the AMM. Have checked the AMM with ohm meter and it seems to be OK. Can run the car with the AMM unplugged. At slow speed it is a little rough but at higher speed it much better.
Noted when I had the AMM plugged in and inadvertently had the hose disconected which goes from the (I think the backfire valve) to the accordion section, the car backfired and has smoke comming from the hose. If I have the AMM unplugged this does not happen. What else can it be????

Not sure what OK measurements on the air mass meter are. Have taken resitance readings between different terminals and not sure what some of them should be. Also is there a schematic of what the different terminals run into. It would help to determine what is causing the problem. Do not like to just change parts until the problem is solved. There should be the old fashioned diagnostic process which would determine what the real problem is.
