1986.5 Toyota Supra HIGH-VERY HIGH IDLE
 

I have an erratic 1000 to 2000rpm idle. does not matter the temp of engine. I can cruise down the road without using the gas pedal (40mph 5th gear). Have cleaned spark plug wells(replaced spark plugs Bosch quad tips), checked for vaccuum leaks, put injector cleaner in tank. Problem began AFTER replacing power steering pump. Also, the BVSV VALVE on the thermostat housing broke off(replaced). Also, replaced battery terminals. Cleaned idle air control valve. Also notice that if you dissconnect the IAC it does not effect the engine. If you dissconnect the TPS the rpms jump to a steady 3000rpms. Any advice will be appreciated.
Thanks,

i have not seen any raised supras. dont you do that to trucks? just curious but why would you want to raise your supra?

i am not discourageing you and your ideas anyway...you can do what you want.

not another one of this things again,, but its your car no matter how senseless the idea is

this is the reason why people dont raise supra,
1) your car is a sports car not an off road machine
2) even if you use your car for rally racing there is still no excuse to raise your car
3) supras are lower to improve the center of gravity and to aide the weight distribution while accelerating and decelerating.
4) it is lowered to improve stability and cornering ability once again this will b achieved with a lower center of gravity
5) car are no longer grease-monkey work it involves a lot of science and math nowadays, physics is a big thing that u wanna consider b4 you do anything that stupid to your car

im not calling your stupid, but what you are planning is
sori if im a little harsh

Take the engine out.....

If you do it, and we see you out in it, we'll roll you over
(or drive right under you) hee hee hee.

I did see a photo of one that had the body set on a 4x4 chasis.

Put it up on blocks to get it 6" off the ground...then put a R.I.P. headstone on it.

Down here in S. Texas the speed bumps/humps are too high for my vehicle. If vehicle is carrying passengers(3) it will SCRAPE THE BOTTOM. tHAT IS WHY, i NEED more lift.

this is when you "slow down" angle your car so it will hit the bump one wheel at a time, this way you wont scrape your bottom

this way, yer bottom wont feel like they have ridin high and dry there partner

What is scraping? The exhaust? That can be adjusted if it is. There really arent any lift kits for sports cars. Just try to avoid them if you can. And it must be ridiculously uncomfortable in the backseat for people. I kno everyone hated the backseat in my car. I'm tall so no one could sit behind me when i drove. I've actually had 6 people in it. That was a fun trip.

damn dude six people, you gotta be talking about two adults and four kids in the back , u have to be

i drove my friend with his date and another friend for shotgun when i drove them to his prom, and i could barely fit them in there, and this are high school students,

since the seats arent that adjustable, and it must be pushed back to lock
we ended up crushing thier knees while were driving

yeah...ive fit four people and all our school stuff. passenger scooted up all the way, person behind me sideways with legs across other backseater. all our bookbags and stuf piled and stuffed where ever itll fit. i find it amazing that you fit 6. you should be a super hero or something.

Yea it was me in the drivers seat, my friend and his 7 yr old brother in the front seat, 2 17 yr olds in the back seat and my friends 7 yr old brothers friend in the hatch.

hey dcrusupra, nice choice of cars...

anyway, on to the topic...Spycialost9999 you can buy some spring spacers from your local auto parts store. There are 3 different types: type one is a set of rubber blocks that you can squeeze in between the coils of the springs once you take the load off them, they are non adjustable. There is a metal type that have a sort of screw in function that you get some adjustablility depending on how far you screw them in between the coils. Then there is a clamp type (normally used to lower the springs by clamping the coils together, but can be reversed so that that you spread the coils farther apart.

All 3 should give you enough lift and in effect raise your spring rates at the same time. I cant imagine doing this to a Supra, but if you need to do it, these "lift kits" should be the easiest and cheapest way to do it.


PS. spycialost9999 - please pay for your TEMS actuators on Ebay...lol...Im not waiting forever! :offwall:
