Might be more due to it being a diesel than an import, since the EPA regs were different and OBD-II was EPA driven.

OBDII was required on new cars and light duty trucks sold in the US for model years 1996 & newer. Some vehicles were compliant a year or 2 ahead of schedule, but being a 95 model it was not required.

Your car might not unlock the TC on idle. My old toyota used to do that but the tracker doesn't. It'll stay locked even with the brakes pressed as long as it is above 36mph. I manually disengage the tc on the freeway and it gives me a bit more coasting before i have to hit the gas again.

This question has been asked many times. For more information than you've ever wanted, just do a little searching. When it's all said and done, MOST automatics are fine for neutral coasting. Some are good for coasting with the engine off, but most are not. Some are not good for coasting in neutral even with the engine on (my wife's Isuzu, for example; a transmission temperature indicator lights up).

Why so high? Mine goes down to 550, same as idling in Park.

QUOTE=BEEF;116232]depending on the year (1995, I know) your car might DFCO which makes it almost useless to shift into neutral. no gas is better than less gas.[/quote]

Rarely. Most vehicles lose more energy from slowing down than they save by not idling the engine. Sure, DFCO means no immediate fuel usage, but it slows the vehicle which then has to be re-accelerated later. Each car differs, but I suspect that most do better with neutral coasting in P&G than trying to P&DFCO.

Plus, just because car can DFCO doesn't mean that it does so immediately and dependably. There's a lot of variables involved in the computer's decision to DFCO, and they are different in each vehicle.

I have asked this before and I never got a really good answer. The best explanation is that the computer is trying to rev match somewhat based on vehicle speed.

Yeah, it's some stupid fast idle built into the computer. The tracker regularly idles at 1100-1200 when in neutral on the freeway. I used to think the transmission wasn't completely disengaging but afterwards if i stop and go into park the idle jumps up to 1200 again and slowly starts to settle down.

On mine if I shift into N @ 60 MPH it falls from ~1,500 -1,600 to ~900 - 1,000. If I let it coast to a stop the RPM's slowly fall until I reach ~ 8 MPH then they drop to ~650 RPM.
