To get to the back three plug leads you have to remove the inlet manifold on top very simple.Try to replace gasket on the inlet manifold ,when removed also pay close attention to fuell lines.

Hi ' I have also the pajero io one time I remove when I Change the spark plugs but I see one of them as got oil at the screw thread. Can you please help.


If there is oil sitting around the hole the spark plug goes into, no worries. If the electrode part of the spark plug is wet or caked with oil then you have either a valve seal issue or piston ring issue.

Have just replaced plugs and leads and the engine light keeps coming on for 1 to 3 mins and when its warm and i go to start it again the engine light comes on and runs a little rough what could this be?


It must be from the rough idling. Check the spark plug gaps and the lead wires if they have good continuity. Check your car manual for the proper gap for the spark plugs. Set it with the use of a spark plug gauge.

95 4 runner rough idle at start


Hi, 1994 4-runner hard-start after 3-4 hrs......All the above are good possibilities and should be checked.....I don't know what changing to E3 means exactly, but if it means changing the spark-plugs, it could be that the plugs are too cold or too hot ....it is probably best to stay with the factory recommended plugs ....some plugs are hot and some are cold ,in case you are not aware of it.......good luck with it....Frankie Don.

My 94 Toyota Camry 4 cyl is running really rough and stalling out once the engine warms up


1. Error Code 24. Intake Air Temperature Sensor.
Solution:
Check the following:
- IAT Connector and wiring.
- Intake Air Temperature Sensor.
- Engine Coolant Temperature Sensor.
- ECM.
2. Rough Idling when the engine is hot.
The following are the reasons due to which the engine can perform bad when it is hot.
- Fuel pump control circuit.
- Fuel pump pressure.
- Fuel injectors.
- Non Return Valve clogged, located on the lower side of car chassis above the fuel tank.
- Engine compression, valve clearance, spark plugs.

Car not starting, whirring once ignition engaged


Check the obvious. Shift to park (also try neutral) If you jump from the battery to the starter directly if it turns then you may need to replace the solenoid. It may also be an ignition that needs to be replaced.

Idles rough runs fine changed distributor may be off one tooth


rough idle may be due to dust in your throttle body, spark plugs but I strongly doubt it's related to your distributor belt
1 - Try a throttle body/air control valve
2- check if by removing plugs from the spark plugs there's any change (no change in engine vibrations means a dead spark plug) you may wanna do this while the engine is hot

My 99 camry 4cyl, has a rough idle and sounds like a misfiring when accelerating when in gear. Any answers to what it could be?


You could sure be running on 3 pistons. Check spark plugs by removing one HT lead at a time with engine idling. One that's dead will not alter your idle speed when disconected. Replace bad plug and check the same cylinder again. If OK fine. If not check whether you are getting a spark to that plug and rectify. If you have both power and a good spark but still without power the check engine - valves and pistons.

1993 nh pajero 3 LTR running on 5 CYL


Hi Roy,
You say you have compression? is it well within the range of the other cylinders? if it is i.e. around 100 psi then possible bent or sticking valve? although you have a spark when plug earthed out of head is there possibly some foreign matter isolating the plug or is it the plug itself breaking/tracking down when in situe?
Failing all these, try a small amount of fuel direct into the cylinder to see if it fires briefly (Not too much just a couple of mls)
Maybe possible Head gasket failure? (I doubt it as all other cyls fine)
Can't think of anything else I would try,
Hope this helps!
