SOURCE: what are the symptoms of a bad egr valve ina 1994 geo tracker?

this may help
EGR Theory. EGR serves one purpose and one purpose only. That purpose is to reduce Oxides of Nitrogen (NOx). Undernormal combustion, Nitrogen(N2)Oxygen (O2) in the air and Hydrocarbons (HC) in the fuel combind into water(H2O) Carbon dioxide (CO2) and the Nitrogen remains unchanged. Under very hot combustion temperatures, the Nitrogen reacts with the other two byproducts and forms Nitrogen oxide (NO). After being released into the atmosphere, it picks up another Oxygen and becomes Nitrogen dioxide (NO2). In the presence of sunlight,
it combines with other compounds like Hydrocarbons and forms Smog. Since exhaust gas is inert (very stable) it doesn’t burn again. So by being introduced into
the combustion chamber, it will lower combustion chamber temps enough so that
the Nitrogen doesn’t react with the other compounds and is passed unchanged out
the tailpipe thus not contributing to smog. Now, since exhaust gas doesn’t burn, it
doesn’t exactly help with combustion. At higher RPM’s, this really isn’t noticable,
but at idle, the reintroduction of exhaust gas will cause a very rough idle and can
cause stalling if to much is introduced into the combustion chamber

SOURCE: 1990 geo metro engine surges up and down when

hi sounds like your engine is surging due to incorrect mixture now your idle screw is on the thottle cable were it connects to the carb and the mixture screw is on the carb body as an approx guide turn the mixture screw fully in then out two and a half turns that should help but y may need to fine ajust later

Gas pedal gets stuck and keeps the car going cant stop without turning the car off


dont drive it. find the cause and fix it now.
Hot and cold engine or BOTH>?
1995 Tracker, no tranny , no 4wd , on engine options stated.
Exact high RPM in neutral, not stated...... 1500 is normal cold.
keeps going in Neutral. (nah , you have 5 ways to stop any car.
key, hand brake, foot brake and neutral. and with 4wd, 1 more neutral.
keep that in mind driving any car.
this car has up to 3 throttle cables that can stick. and more!

1: floor mats hit the pedal>? ala. Toyota style (lawsuits)
2: the three cables are, throttle. , cruise and A/T transmission kick down cable. if car is M/T and no cruise it has 1 cable.
so disconnect it, throttle fixed? (disconn,. 1 by 1, bingo?

no cure?, then its not the pedal , you meant just high idle.
yes, replace the cable or bad parts three.
ok say its not the cables.. (tests proved that)
the 95 came with 2 engines, 8valves and 16valves,
they work differently (8v love so race, 16v loves to stall)

1: ISC Stuck open, common.
2: 8v, any air leaks at all , will cause super high idle speeds.
3: throttle valve in the throttle body is stuckopen (gunk) or the return spring broken (very very rare the latter,in fact never heard of one breaking)
4: IAC (thermal idle control stuck open ,(my 97 was). and lots more.
5: on the 16v it takes 2 failures. to make high idle.
gross rich running engine (cold engine its normal) and any air leak
once hot the engine can not race unless there is huge overfueling
and an air leak.
6: the 8v has this device on the side of the throttle body.
called a dash pot. its just a fast idle vacuum servo.
if stuck open the engine will scream full time....
7: ECU stuck in limphome, can cause too high idle speeds.

we need to know which engine
http://www.fixkick.com/find-parts.html
8v or 16v first.
then does the idle race hot or cold or both (engine temperatures)
if it races , then how fast?, RPM the dash tachometer tells you that.

it can be as simple as a 50cent hose cracked.
to a dead ISC. (idle speed control) IAC is thermal idle air controller.
the IAC must be closed on a hot engine,
if the the engine never gets hot,it will scream full time.

1990 f150 larriat. V-8, I believe the engine should idle around 750 rpm. I tried using a timing light and adjust the timing but the it would not work with advancing the timing. Is there anything else...


YOU CAN PUT THE TIMING BACK TO ORIGINAL POSITION! ON TOP OF THE MOTOR! IF IT IS CARBURATED, YOU CAN ADJUST THE IDLE SCREW TO RAISE IDLE! IT WILL BE A SMALL SCREW LOCATED BEHIND THE THROTTLE PLATE! ON FUEL INJECTED MOTOR, IT IS LOCATED UNDER THE COVER WHERE THE THROTTLE CABLE GOES INTO! YOU WILL SEE A SMALL SCREW BEHIND THE THROTTLE PLATE! THE PLATE IS A RECTANGULAR PLATE THAT YOU CAN MOVE TO INCREASE THE IDLE BY HAND! I OWN A 93'!

1990 tracker idles high all the time unplug map sensor on fire wall it idles down but runs sigh smokes


check for vacuum leaks. this can be done by waving a gas torch (propane) near the intake piping between the throttle body and the intake manifold with the engine running.

The throttle is running at a high rpm about 1000 and throttle cable has some slack in it usually idles at about 700 rpm can it be adjusted or do i need a new cable its a 1998 gmc sierra 1500 5.7 litre


The throttle cable is probably ok. I would be more likely to suspect the idle air control valve/solenoid to be causing your trouble. Sometimes trouble with the EGR valve not closing all the way will cause this problem as well.

High idel


You may have a bad control valve or regulator. Did you adjust the idle properly?

1. Disconnect the connector on top
2. Adjust idle to around 650-700k rpm
3. Reconnect the electrical connection

After reconnecting, the idle should jump up around 700-750k rpm.
The idle screw is fail safe setting in case the ecu cannot set the idle. The rpm's set by the idle screw are supposed to be below the ecu/stock idle.

If this doesn't work, you may have a dirty or bad Idle Air Adjuster and/or Air Regulator. For information on cleaning that, you can refer to this page http://s95014253.onlinehome.us/63104/157335.html

You can test the IAA by supplying power to the plug with the car off. Listen for any clicks or humming. That will signify that it still may be working but is possibly stuck. The Air Regulator is for high idle for warming up your car. It has a bi-metal spring inside that rotates a disc closing off an airway to bring idle to normal after a couple minutes. If it dies it will stay open and give you permanent high idle. If it gets clogged usually no high idle for warm up.
You can remove it and peer through the end. If you see a thin sliver of light, it's open. Connect 12 volts + & -, wait a few minutes and see if it's now closed. If not, it's likely dead. It can be opened and cleaned if that's the issue.

You are really onto it! Either the TPS or the cable from the peddle. Do check the cable first. Frankster016
