Reply to "IR injection maintenance"

First off, the heim joints are stainless steel balls in nylon races. You do not lube them at all.

Second, if the throttle linkage is assembled correctly it should work free and easy with just the return spring in the Pantera throttle cable.

If you will remember, I have previously advised that you need to determine if it is the throttle cable that is hanging up.

You do that by disconnecting it from the throttle bodies and operating it. This will at least eliminate that cable from the issue if it is ok.

It should work easily and snap back when you release the pedal. There shouldn't be the slightest indication of it hanging.

If it does hang, you have two choices. Fix it or replace it BUT remember, these cables have an inherent internal issue that the new one will also have. Fixing that issue seems to me to be the permanent fix?

The other thing is that with a throttle return spring in the linkage of too much pressure OR in the WRONG location, you could have worn throttle shafts in the throttle bodies themselves.

Do the throttle cable test. Then go to step 2.
