max idles high after hwy use
my 91 max idles at about 1500 rpm after I cruise on the hwy sometimes. If I let off the brake at a stop light when this is happening the car tries to drive itself (30-35mph). anyway once I stop and put her in park I can rev the engine past 3000 or higher and then the idle eventually drops back to down to 800rpm or whatever it usually idles at. Any Ideas? Fuel filter? Note the trottle cable does not stick this is not the problem. Thanks

I guess you could clean the t/b...See if that helps....

What else could cause this symptom
I don't want to have to live with the dumb excuse on its 17 years old so it can be a screwed up car I have the same prob but I just let it idle down before I change gears so it isn't as hard on the trans ....
Thanks Guys

It could be other things, such as a bad temp sensor that's telling the computer the engine is cold or a pollution control. As I remember it the idle comes up on the car under certain engine conditions (which I don't remember) that produce pollution. The car produces more pollution at idle. Perhaps its a bad O2 sensor that's indicating too much fuel in the exhaust (just a guess). There's also the power steering and a/c idle up relays and solenoids that could be acting up.

word.......But why does my car have two cams gears if it is a sohc. I have had the timing cover off and it has two what would appear to be cam gears
what years have the VE?

what years have the VE?
2 cams...one for front 3 cyl the other one for rear 3 cyl.
on the VE (DOHC) there's 2 cams on each side...so really 4 physical cams in the car.
92-94 SE models have the VE motor.

for example...
a DOHC inline 6 cyl would have 2 physical cams but it's still called DOHC motor.
a DOHC V6 motor would have 4 physical cams on the motor but it's still considered a DOHC motor since there's 2 cams per cyl head.

Hell, now that you're messing with the air intake tube might as well take it off and clean your throttle body and butterfly plates too.
Have fun

Wierd, had the same problem today. Got off the highway, into the city and into my driveway, and noticed that the idle was high, idling at 1200RPM or so. Revving the engine didn't do anything. Turned the car off, started it again, and idle back to normal. Car ran perfect all summer, and still no problems, first time it's done this. Wonder if it's outside temperature related somehow? I'll keep an eye on it, and planning to clean the IACV this weekend. I'll let you know if it comes back.

My 87 2nd gen is doing basicly the same thing after 88 W block engine swap.
But it idles at like 2k and no matter what i do , adjust tps , Adjust throttle cable and dissconnect the ICV.
..
When istart mine up ill have to rev the engine up to like 2 k with the gas pedal and then hold it there for about 1 min then let off or it will stall ...
But once i let it sit for like 5 mins the idle will go up to like 1.5k and then i go drive it around and stop at stop signs and lights it will be at 2 k and i will have to pull the gas pedal up with my foot and then it will idle back down to 1.5k...
Never ending issues!!!
