RPM doesn't drop after shifting when the Heater is on???
97 B2300, 5 spd.
This happens ONLY when the heater is on...
Let's say I am in first gear.. I go up to 3,000 RPM then hit the clutch to shift into second, after I hit the clutch, the RPM sticks at 3,000 RPM and doesn't go back down unless I slow down to like 10MPH and getting ready to stop at a stoplight or something.
If I'm about to go down a hill, I usually just take it out of gear and leave it in neutral while rolling down, but when I hit the clutch, it stays at whatever RPM I was at before, defeating the purpose.
The weird part is that when it is happening, and the RPMs are stuck at 3,000+, I can turn the knob of the heater to the off position, and the RPMs drop instantly back down to idle (800-900).
When the heater is off, I have no problems at all. This is really beginning to get bad because it's getting colder and I need my heater to be on. Switching into a higher gear while I'm already sitting at 3-4k RPM isn't good at all. It grinds into gear often.
Does anyone have any idea what it could be?
