    I have the exact same problem about a year ago the mechanic told me that it was the idler control (i think), however it has started doing it again recently it also overheats in the morning after about 10 miles and then drops back to normal about 7-10 miles later.

    I have a 94 p/u 22RE that does the same thing. Idle will surge up and down. It appears to get better when warm.

I had a simular problem and it was actually low coolant and the radiator was bad.

Hi there, the solution to this may/can be the one-way valve that's located either on the intake manifold or on the brake-booster, to check this valve remove the hose from the intake and when either blowing air through or pulling air through it, it should lock the vacum you creating...oh clean the valve 1st and use your mouth. post again if this dont work.

94 toyota camry has low idle and stalls when in reverse


Idle adjustment should be @600 to 700 RPM with the car in gear and emergency brake on if the car is an automatic trans. Adjust idle accordingly. If a standard the idle should be @ 650 RPM at idle.

Check the vacuum hose from the engine to the power brake vacuum reservoir, it make be loose or cracked and will cause an erratic idle because of the vacuum leak. Please rate this answer, thanks.

Car will not start without pressing gas pedal to keep idle speed up. If I keep idle at 900 RPM or higher it runs as long as foot is on gas pedal. It then stalls out when I take foot off gas pedal. No...


Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.

Engine increases rpm when brake pedal is depressed


Inspect brake booster vacuum line from engine intake to brake booster for leaks also inspect brake booster check valve, more than likely your brake booster is causing a vacuum leak to your Intake thus leaning mixture wich increases idle rpm

94 Toyota 2.4 engine idles fast. when warms up it starts surging


sounds like an Idle air control valve or a positive crankcase ventalation valve(or pcv valve). use some intake cleaner in the air intake and take the pcv valve out and shake it it should rattle and move freely. mike
