SOURCE: fuel starvation mazda bongo

Bongo 2.5 Tdi. WL-T.
Everything fine untill 20 minutes after fueling up the engine started to run rough when stopped(at idle). I shut down. Couldn't restart. Next morning started up and ran fine. later on, wouldn't start easily and when it did couldn't rev above 800rpm. another time started but no power.
Seems like fuel starvation. I just bought the van and have sent away for workbook, fuel filter, glow plugs etc. Where is the fuel filter located? I see where the fuel line goes in to the FCU (or flow devider) is this where i should check presssure. I know a little about petrol engines but nothing about TDI. Any help would be greatly appreciated!
Thanks,
Rowan

SOURCE: mazda bongo 2.5 turbo diesel 1996. over heating

no im a mechanic it sounds like that you have an air lock in the cooling system .i am familiar with ford freda and bongo and the design where the engine is is a bit far from the radiator ,so the problem with air locks magnifies.really the solution is just drain the water and refill it slowly while you are pressing and releasing,just repeat the action on the top radiator hose to get rid of any air trapping within the system,it's as simple as that really.you want it to have just water and no air as this will cause a blockage.

SOURCE: cannot control engine rpm mitsubishi lancer engine

Your IACV idle air control valve has gone bad . When you put the car in gear does it take off and accelerate to about 50 MPH without touching the gas pedal ? Had the same problem. Part from Mitsubishi is about $435 PN # MR578268. It is about $30 to $50 dollars on any other car. If this is the problem, the IACV is located on the throttle body and is held on with three screws. I purchased the whole throttle body at a salvage yard for $40, took the IACV off and put it on my throttle body. Car works normal for now, I am looking for another spare. If enough people complain to MItsubishi and www-odi.nhtsa.dot.gov

PO440 on 1999 Pontiac Montana. Is it the purge solenoid valve? And how can I get to the purge valve to replace it?


It sits on a bracket. In the center of the bracket use a small screw driver to bend the center piece out away from the valve. Then work the valve off of it. Pull it up to see it. Unplug it and remove the purge lines.

Car runs fine otherwise, yet it revs itself up to over 22k rpm and smokes like a beast. This will go on for some time, then it will rev back down, and stop smoking. Then it will rev back up and smoke.


With due apologize, the very first thing which I would like to amend is that it is not 22 k but it is 2.2 k (2200 rpm).
To solve the problem please check the following:
- Vacuum leaks. (PCV valve, A/C idle up vacuum switch and actuator, vacuum hoses routing, gasket intake manifold, distributor vacuum dash pot.
- Valve clearance.
- Ignition system.
- Carburetor vents and lines for clogged.
- Idle speed solenoid switch and its connection. (Remove the solenoid, put a finger on its hole on the carburetor, start the engine keeping the finger on the hole. If it maintains the stable rpm replace the solenoid or check the voltage on the switch).
- Adjust the air fuel mixture.

1987 ford tempo 2.3 Litre fuel injected will idle


this sometimes occurs with age due to egr and intake becoming carbon filled , inturn requireing more vacuum inturn raising rpm to keep up , check all vac lines for poss leaks this will cause prob , to check for leaks crank engine let idle use can of wd40 or starting fluid and spray lightly around suspected area , if rpms raise when u spray then u have found ur leak

Air conditioning causes car to idle or die.


Depending on whether your car is Injected or Carby induction, The aircon system has an IDLE UP circuit which is supposed to raise the Idle while the Aircon Compressor is engaged. The Compressor cycles on & off to charge the system pressure as required. The Idle up system typically uses an IDLE UP SOLENOID which is usually mounted directly on the throttle linkage at the Carby or Throttle body itself, or a Vacuum Solenoid which switches vacuum to a Diaphram which is connected to a linkage on the Carby or Throttle body itself, or a Vacuum Switch which ports air into the throttle body to raise idle (This type on injected vehicles only). It sounds as if the IDLE UP system has failed or is not adjusted properly. Revving the engine spins the compressor faster thus charging the system sufficiently to dis-engage the compressor, which in turn removes the load from the engine, allowing it to idle again. A simple way to test is to disconnect the Aircon clutch wire (make sure it cannot fall into belt) & switch on the Air with the engine running. The RPM should raise typically around 300 RPM. If it doesn't the IDLE UP is not working. Hope this helps.

I dont know where cirtain hoses go, i have a 1994 Ford probe with a mazda mx-6 motor, where does the hose from the fuel filter go? Does it go to the carb, and if yes. where?


94 ford probe does not have carb. it is fuel injection. that hose from fuel filter goes to the fuel rail on engine. if it is a vacuum hose it should go to the fuel regulator also on fuel rail.hope this helps
