A large rubber hose feeds air to the large block with "RE-EGI" cast into it. Between that intake hose and the RE-EGI block, called the dynamic chamber, is the throttle valve. You can adjust the idle speed by adjusting a screw in the top of the throttle valve to 800 rpm.

85 ford ranger idles up high then drops down and will die unless give it a little gas. heard it could be egr. where is that on motor? thanks for your help!!!!


it could be the egr valve, located driverside at rear of engine, will have an electrical plug in to it also,simly unplug and 2 bolts that hold it onto the motor. but i do suggest you check it for a bad idle control sensor 1st look on top of motor at the air induction for a round silver canister about 4inches long and 2inches round with an eletrical plug in ,it will have 2 small bolts holding it onto the motor. i suspect that to be your problem, unless it misses bad while driving it. if your only problem is with the idle, i suggest you start with that idle control sensor 1st and as always thank you for choosing fixya.com

I have a 1986 toyota 4x4 pickup. It starts fine and idles good but when you step on the gas the motor acts like it is flooded. I checked the timing changed the spark plugs and the fuel filter and no change...


Had the same problem on an 87 pickup not 4x4. Check the rubber fuel line from the tank to the engine, mine was so old that when the engine tried to **** a lot of gas the rubber line collapsed and restricted the amount of gas getting to the engine.

When you say it's destroying the air filter---do you mean it's all sooted up ?? I am assuming that what you mean.
Try disconnecting the vacuum line at the egr valve and see if that helps.
But it sounds more like a plugged up exhaust system.Try disconnecting or looosing the flange before the cataylic convertor and then see how it runs.

Poor idle


my truck was doing the same thing, i tried to adjust the idle screw and replace the ignition system but it didnt help. What i did was replace the carb with a webber and the problem was solved. I'm not saying to buy a webber but you might just need to rebuild your carb or something similar
