I've been having this problem for awhile. The car idles nice, but as soon as you put it into R or D, it slams roughly into gear and sometimes stalls. On wet or smooth pavement, the tires squeek. I can't imagine this is good for any of my drivetrain. Would turning the idle down help out? I think its at 7-800 rpm. The tach is still the 4 cyl model, so I divide it in half. Thanks for any ideas.

800 RPM should be ok, but from what you describe it sounds like it is idled way to high. Are you sure you can trust the tach you have?

I doubt I can trust many things with this car. It sounds higher than 800 rpm, more like 1000-1200. I forgot to mention, this is an FMX.

Reason I ask is because my 4-popper does the same thing, but it is because it idles at 1100 (I don't know why it idles that high or do I care cause it's just my beater) But it does the same exact thing you are describing.

?????

why dont ya flip the switch to 8 cyl?? (or, do they have that after the 79-86 cars, i know they did...)


anyway, sounds like the idle is too high, and/or it has a mal adjusted tv cable.

Tach doesnt have a switch. I think I found what it is. I got under the car with the tranny in neutral, and the driveshaft moves back and forth a bit before the wheels start to move. This leads me to believe that the rear end may need to have something fixed inside.

I can see the pinion gear moving too, before the wheels are moving. Well, I can't see the gear itself, but the shaft the driveshaft bolts to.
