I jus recently had my 91 240 "fixed" but one of the plugs keeps wiggling out when i drive, so i end up going from driving on 4 cylinders to 3. I can push it down but it eventually pops out again. Does anyone have any tips on how to get this fixed and how much it will run me. I'll do it myself if its sumple enough. I just started getting into cars to please forgive my ignorance. Thanx

 

you mean the spark plug or the spark plug wire?

if its the spark plug that falls "out" then you gotta helicoil the threads.

if its the spark plug wire, get a new set of wires.

 

its the spark plug. sorry for not clearifying. how do you "helicoil the threads". once again sorry for being stupid

 

I think you may be confused on the terminology. Just so we are on the same page, you are pushing down on a black piece of rubber with a wire connected to it right?

 

yes, ha thanks for putting it so simple.

 

if you haven't already fixed it, helicoil is a tool to re thread your spark plug holes. you can get them at any napa. but basically i you can do it on the car (but i wouldn't) and retap the hole tiwh a tap, insert your helicoil and you are done. easy fix.

 

Ok, you need a new set of spark plug wires then. The spark plug is what screws into the head and is what the end of that black wire (spark plug wires) attaches to at the bottom of that hole.

 

i still have no idea what hes talking about. i'm just guessing and seeing if he aggrees.
