No power when transmission is in drive?

Hi,

When there is a power loss, my first suspect is the catalytic converter. Are you hearing any odd sounds or odors from the exhaust?

Take a look through this link and let me know if anything mirrors what you experienced:

Let me know.

Take care,

If it is in drive, does the vehicle move or does it not rev? Also, have you checked for diagnostic trouble codes? In 1987, they used an OBD1 system. You can retrieve codes by cycling the ignition key. Take a look through this link and let me know if you get any.

Okay, I can tell you are upset. Keep in mind, I am not there so I have to understand what is happening.

In your original post, you indicated, "Manually moving the accelerator linkage, engine revs. If in r, it also revs but in d it has no power." Does it rev in drive and only barely move? Is the transmission slipping?

Can you please shoot a quick video with your phone of the problem, so we can tell for sure what's going on. You can upload it here with your response.
