Question about 1992 Daihatsu Rocky

Open Question

Idles too fast 1500 rpm, then when motor warm races from 1500-1800rpm, unless a/c on, then levels at 1500

I just changed oil & filter and wife drove car 5 miles and embarrased self at stop lights, as motor raced at idle from 1500 to 1800rpm, except when a/c was on then idled smooth but fast. (Everyone thought she wanted to drag race... Rocky?... Sure) Found no loose wires, no cracked, broken or loose hoses. Very light user, hadn't driven car over 100 miles in last 3 months. Is in mint condition. 132,000 miles. Wife's 2nd car. THanks, Richard (916) 961-5966

You need to check the throttle stop cushion is making contact. The engine will hunt if you have air in the throttlebody coolant pipes, if the coolant sensor is faulty or if the TPS isn't calibrated.

You may find the throttle position sensor (TPS) needs adjusting or the throttle plate is gummed up and not closing completely. The other two possibilities are the coolant temp sensor and air temperature sensor.

Run a diagnostic per the following:

1. Check your water sensor and plenum temperature sensor.

2. The throttle body has a wax element air valve used for cold idle. As the water temperature increases, the wax element closes the idle fast port. Being the highest part of the coolant system you may have an air lock, which can be solved by bleeding the hoses on the throttle body.

SOURCE: My 1989 Daihatsu Charade CLS (3 Cylinder) has a low idle

The E-brake light is on because the brake is slightly on, or the fluid is low, or the brakes are failing It sounds like the fluid is getting low from normal brake wear and not a problem. Just get the front brakes cheched and replaced. Don't put any fluid in because the new brake pads which are thicker will take up the space the fluid has dropped and push the fluid back to the correct level

Your engine is shutting down at idle because of a a bad seal on the engine induction system. It is the big duct that connects to the engine air intake. Leave the car running at idle, E-Brake on, and squeeze the big black duct going from the air filter to the engine, Does the car shut off? Next check small little hoses that attache to this big air duct. Try moving them a little to see if the engine runs different.

If these are good then I would shut off engine and remove this duct. A hose clamp holds one end. A slotted srewdriver will work to remove this clamp. The other end, at the Air Filter simply unclamps by hand.

The Throttle Valve is the first thing you see in the engine, it is inside the intake just after the duct you removed between the Air Filter and Intake. Have some one open the Throttle by stepping on the gas pedal and see if it is clean around the edges. If not, use some cleanning alcohol from your medicne cabinet to clean this area. A toothbrush will get into the tight spaces. Wipe clean with paper towel. Autozones sells a special cleaner called Throttle Valve cleaner spray. Use this not Carburator Cleaner.

If it still runs bad a idle the idle valve could be dirty and now you need more tools to remove it and clean too.

Idle rpm too high


You don't say if the engine is carb or fuel injected.
If it has a carb, it could be sticking linkage for the fast idle to the choke.
If it is fuel injected it could be a faulty idle air control valve.
Or it could be something holding the throttle open like a binding cable.

The idle on my '90 4runner 3.0 fluctuates and idles at 1500 rpm any ideas?


You should remove inspect and clean the idle control valve on the throttle body. This can become clogged over time, or the motor itself can become worn and may need replacing.

Idles fast problem


That would be your engine "choke" functioning. It's not a problem. The choke engages when engine is cold and shoots extra fuel to the cylinders to idle the engine up especially in cold with. Once the engine has sufficiently warmed up, the engine will idle back down.

2006 chevy 2500 express cargo van .What is a good oil pressure for this van. it has 150,000 miles runs great


60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

When bought engine idled @ 800 rpm when warm, now engine lite is on and engine idles rough @ 500 to 600 RPM. Replaced rack and pinion, power steering, checked wires, replaced sparkplugs, # 1 plug was in...


could be numerous reasons. this is your best bet take it in to a mechanic and have your engine codes scanned. it is a minimal charge, some even do it for nothing it only takes 10 minutes.this will point you in the right direction.

Idles up and down after warm up


THE COOLANT LEVEL IS LOW

on the older hondas even the newer ones idle speed is coolant temp controlled.

when the engine idles up the electronic coolant temp sensor is submerged in coolant and reads warm, so the engine computer idles the car down. the coolant level if low than drops from around the coolant temp sensor and it says the engine is cold, so the engine computer idles the car up.

which results in the constant rise and fall in engine rpm.

ADD COOLANT TO THE RADIATOR AND WATCH THE CAR MAGICALLY FIX ITSELF.

1987 volvo 244 intermittent fast idle floods after shut down


The coolant temp sensor sends signal to the ECU and the ECU adjusts the idle RPM. When the coolant is cold, the engine requires more fuel to sustain idle with thick oil (oil gets thicker & more viscous when cold). This makes the engine to idle at faster RPM but it should settle down to 850 RPM or so after the coolant warms up. The sensor is nothing but a thermistor; a device that changes electrical resistance according to the coolant temperature.
