Do you get spark at the plugs?

Bessie, you'll need to do some good ol' fashioned troubleshooting. You need to establish that the vehicle is getting both IGNITION SPARK and FUEL. When you figure out which the vehicle is NOT getting, you can begin to troubleshoot from there.

It is usually coming from the spark plug wires( leak spark). Spark to ground or piece of metal.
To find out exactly take an empty spray bottle fill her up with water and add 2 tablespoons of salt. With the engine running a light spray of the mix on spark plug wires you will see the spark leak and proof the spark plug wires have a defect. if so replace all spark plug wires that should solve your problem.

Hope it helps.

wiring problem

Hi you know when you changed the plugs did you make sure that the little cap was screwed on properly on top of the plugs, this is the part the plug lead pushes onto, check this as it seems this could be your problem.

other possible causes could be loose plug leads, wrong spark plugs

first check the little nipple on top of the plugs is tight then let me know what you find ok

plz rate this solution as i have a whole page of unrated posts, thanks

hi dispite all your hard work the error says you have a missfire /random cylinders hope this helps if so give the answer a rating please thanks pete

You may also have to check the MAP sensor at the intake. Fuel mixture may be incorrect. Also check the status of the spark plugs if it is fouled or soaked in gasoline.

sent it to a garage to repair, dont know what they did thanks pete
