What engine, what year model? When you get down to about an 1/8 th of a tank pour a big bottle of SEAFOAM gas treatment in you tank. Then go run it out at high RPMs low gear our 100 mph doesn't make any difference. What this will do is clean your fuel injectors and plugs. Think of fuel injectors like a bottle of wind spraying fuel at your spark plugs. If the nozzle on the bootel is plugged it won't mist well, same with fuel injectors slow city stop and go traffic leaves carbon deposits on the "spray nozzle" this will cause hesitation in stop and go. If your savy about throttle bodies if it has more that 80k you need to pull it and clen it. Throttle body plates and intakes+ the senosors that go with it really get carbon up bad. Make sure you use the throttle body cleaner and oxeygen sensor cleaner exactly where you should this one project you cat just brake fluid to clean with. Hope that helped, oh 3rd possible but not likely cause fuel filter slightly plugged. Send back data on miles, size of engine, year, make, If this doesn't solve your problems, do you have any check lights on? Bret

Engen problem and missing


Sir, your question is not very clear, but I will still try to post a solution here. Engine missing could be due to any problem in fuel system, ignition system, engine or ECM as well.

LOW ENGINE IDLE SPEED (Poor idling):
-Throttle body (do the cleaning and idle speed learning)
-A /C signal circuit
-Fuel pump control circuit
-Fuel pump
-Intake system
-P C V valve (clogged or open) and hose

ROUGH IDLING:
-Cylinder Compression
-Ignition system (Igniters, spark plugs, wiring harness)
-Spark plug fouled, gap too wide or too short. (1.00-1.1 mm)
-Fuel injector circuit
-E C M power source circuit
-Fuel pump control circuit
-Fuel pump (required pressure 44 psi - 49 psi)
-Throttle body (cleaning)
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Heated oxygen s ens or
-Mass air flow meter
-Idle hunting
-Throttle body
-Intake system
-P C V valve and hose
-Air fuel ratio sensor
-Mass air flow meter

HESITATION/ POOR ACCELERATION:
-Fuel pump control circuit
-Fuel pump
-Spark plug
-Ignition system
-Fuel injector circuit
-E C M power source circuit
-Mass air flow meter
-Throttle body (do cleaning)
-Intake system
-Valve timing
-Cylinder Compression

My 1996 Mitsubishi Montero will start but not idle at all once driven. My father-in-law suggests adding some Sea-foam to the vacuum hose and the gas tank to help. My question is; where do I find the...


Back in the good old days, engines had various vac hoses that controlled other devices including the PCV valve. The idea was to use one of the vac hoses to pull SeaFoam directly into the intake and help clean deposits off the intake valves.
Today's engines have very few such hoses.
And in your case, the problem is probably dirty injectors or the throttle body itself.
So I would put the seafoam in the gas tank, but also check the throttle body to see if it is gummed up. You can use spray carb cleaner if it needs to be cleaned.

1994 gmc pickup- starts but when you put it in gear it dies, give it gas it will run but not good


It sound like your idle air control (IAC) valve is dirty and the fuel injectors. Try cleaning the throttle body and IAC with throttle body cleaner, if it's really bad you may have to use two cans of throttle body cleaner to make sure you have all of the carbon and varnish cleaned out. If this does not help, then there is a good chance that the IAC has gone bad and needs to be replaced but also check the wire harness to the IAC and TPS on the throttle body. Good luck and hope this helps and it would not hurt to replace the fuel filter also.

When i press accelerator engine is cutting ....


The van may just need a good tune up.

  • Replace the fuel filter
  • Replace the air filter
  • Replace the PVC valve
  • Replace Engine oil and filter
  • Replace the Spark plugs
  • Clean out the Throttle body with throttle body cleaner
  • Clean out the MAF sensor
This should help you get your van running 100% soon. If your on a tight budget, start with Cleaning the throttle body with spraying throttle body cleaner into the throttle body and cleaning up the MAF sensor with MAF sensor cleaner, just follow the instruction on the can. Then replace the PVC valve and add fuel injector cleaner in to the gas tank. This should help your engine running better and then you can do the rest of the work to complete the tune up. Good luck and keep me posted. If you go to Auto Zone, you can get all the things you need and they can scan your van for any DTC codes that may also indicate what issues your engine has.

1996 Mitsubishi Montero has no power..


My 96 Pajero SWB 3.0 would loose power as soon as i accelerate. It feels like the spark plugs are miss firing or if the engine was flooded.

I did a general service which included oil change, oil filter, fuel filter, air filter, spark plugs i checked my O2 sensor, dissembled and cleaned throttle body and sensors. Cleaned air intake sensor as well as the distributer etc.

Problem not solved, still loose power when i accelerate....can it be something wrong with my ECU??

My A/C control isnt working at all. Found a 15Amp fuse that was blown but when replaced it shorts again. Where can i get a wiring diagram of the heater/a/c system for my vehicle model?
