1990 Toyota Pickup Idle engine surging?

Excuse my lack of car talk, but I don't know anything. My 1990 pickup's engine surges every time I'm its idleing. Its automatic 4cy 4WD. My regular mechanic can't figure it out. He aint the most knowledgeable, but hes very fair in price. So I jumped on the internet to try and point him in the right direction on why it may be doing this.

My gas milage right now is 13mpg city. Its hurting me because I am a contractor that cruises around the city all day. Any help would be much appreciated!

If the engine is surging/idle increasing and then decreasing at idle, have your guy check for leaks between the air flow meter and the engine, also, if no leaks are found, Check/replace the throttle position sensor

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.

The Idle Air Control Valve (IACV) may need cleaning or replacement.

This valve lets air bypass the throttle plate so that the engine can idle. The more air, the faster the idle. If this valve is sticky, the computer may have a hard time regulating the idle properly and may surge.

You have extra air leaking into the intake manifold that mimicks a throttle that is open further than it really is. Check for vacuum leaks.

High idle@14000 and rpm surge between shifting to 25000


you could have a vacuum leak that is mimicking a throttle that is open further than it really is. Also could be timing that is too far advanced.

Is the check engine light on?

A major cause of surging is either air leaks between the air flow meter and the engine intake manifold, or a bad or mis-adjusted throttle position sensor.

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
