Shaking during idle when warm.


try injector cleaner or newer fuel cleaners, try octane booster, sounds like a fuel delivery symptom but the temperature factor is a worry. I would guess injectors.

Power steering max


Hi Sherman

You have to do this test to find out why the steering is heavy.
after you check the steering fluid level and top it up if needed.
start the engine let it IDLE try to turn steering and feel how hard or soft is.
Now rev the engine up to 2500 rpm and keep holding the rev. test the steering while you still holdind the rev.
if you feel no difference, the problem is the steering rack it self.
if the steering get softer while you rev up, the problem is the power steering pump.
Good Luck

They make a connector for the sender unit and they have to usually be replaced. Watch which way it goes on since they are a little cumbersome plugging back on...I prefer soldering the new connectors on too.

My 1987 turbo toyota supra will only rev up to 2500 rpm then cut out like a governer. when it drops to about 2000 rpm it will rev back up only to 2500 rpm. at an idle it runs rough


The throttle position sensor has an idle switch in it that tells the car's computer that the throttle is positioned at idle. If the idle switch sticks in the idle position, the computer will not allow the engine to rev more than 2500 rpm. In your case, I think the switch is stuck.

First, see if you can get the trouble codes to come up. Rig a jumper wire and jump between the "T" terminal and the "E1" terminal in the car's "Diagnostics" box. It is a small black box on the driver's side of the engine compartment near the battery. Open the lid and on the inside of the lid it has a map of the terminals.

Once you hook up the jumper wire, turn the ignition switch to on but do not start the car. If there are codes, the check engine light (orange) will blink the 2 digit code. It blinks the first digit, pauses, then blinks the second digit. The code for the throttle position sensor is code "41". That is, four blinks...pause...then one blink. If this code comes up, change the throttle position sensor. (If there are no codes, the check engine light will steadily blink once per second until you turn the key to off.) Don't forget to remove the jumper wire when you are finished.
