I just got this car (91 SE) and I am trying to get use to the car.
When I accelerate to a certain speed (example: 15mph) and release the accelerator the car seems to maintain that speed at level ground. Only when I hit bumps, go up hills or tap the brake will the speed of the car be reduce to a lower speed but becomes constant at the lower speed when level ground is reached again. I do not have the cruise control on and this happens at low speeds (< 30mph) also.
I can not remember if the RPM drops after the accelerator is released.

Am I just nuts and what I am noticing is just the car's ability to coast further than the other cars I am use to?
Or do I have a problem?

When at "park" the engine will rev up when the accelerator is pressed and immediately drop when I release it.

 

ground level is reached again? So let me get this straight, your car goes airborn, when you hit the accelerator?

 

 

If the throttle is sticking the test I did when at park will leave the RPM high when I release the accelerator?

I'm going to try to test the TPS and look at the ECU code.

Any other sugguestions?

 

Well I've never driven an auto until I had to drive my mom's Taurus once last year, and I noticed the same thing. Since there's no direct compression slowing the engine (and car) down like when you take your foot off the gas in a stick-shift, it just coasts forever. It's so annoying! So if you're used to manuals, and it's an autp, thats probably why. It's not a problem just another annoyance of an auto.
