    Do you mean when you accelerate it misfires? Spark plugs and spark plug wires. Check distributor cap and rotor first.

Check coil for cracks and weak spark on one side. Check pcv hose that connects to the intake manifold as they will collapse and leak. It will turn the light on. Check while running.

My jaguar (lpg gas) says limited performance


hi your issue is that your car which starts with petrol then switchies over to lpg for which youll already know ,but the problem lies within the cylindar heads as it can only be 1 of 3 things =1, your valve seals are worn excessively due to the lpg as that runs at a higher heat density which stretches the valves which in turn causes then to wear and that reduces the power ie lack off,as it puts the ecu into limp mode (safe to protect your engine) as its a common fault on ALL lpg conversions.as that is also the knock on effect with your master servo (brakes).as i fix approx 3/4 a month.
hope this help's to clarify what is wrong ok

My ford focus' check engine light just came on on the way home from work and is flashing periodically car seems to be running ok so far can you help


flashing check engine lights mean that there is a critical failer that could cause severe damage. they should not be taken lightly. a missfire can cause the light to flash. the best thing to do is take car to a shop or an auto parts store to get the check engine light read. check engine lights dont always tell you exactly what is rong, but this will give a good direction to start in. a check engine code would be helpfull in diagnoseing the cars problem.

Engine management fault light permanently on caused by what?


If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

Only misfires when running on LPG, have fitted another twinpack coil, platinum plugs and checked and measured the leads. What should the plug gap be and what else should I check?


you have a problem with the gas supply ,sounds like the mixture and no dealer has the equipment to test it ,take it back to the lpg installers
