loose spark plug?

Question

I was just wondering if a loose spark plug can cause a car to break down on the side of the road?

Answer 1

Doubtful.

It may cause it to run bad, but not make the engine quit running.

Answer 2

yes it can ,i own a shop,and it will cause one to stop running especially on a 4 cylinder engine,one plug on them stops firing,good,and it will fall on its face,and you may also have other problems with it ,but yes if you have a real loose plug that can cause it,it might be time to give it a good tune up,this sounds like the right time to do this,good luck i hope this helps.

Answer 3

the car would RUN hard or rough... I have never heard of one stopping....

I doubt it would as you have 5 or 7 other cylinders running...

I would guess if the car runs when it is cool then stops when hot it would be a senors.... on some older cars this can happen... for the life of me I cant remember the name of the senor.... which sucks.....brain fade

Answer 4

Generally no, but if it pops out you'll have a problem, and it can damage the threads when it does pop out. If its just slightly lose it shouldnt have a substantial effect on the way the car runs.

Answer 5

Yes it can, the engine loses compression and power, this could cause it to stall.

Answer 6

it shouldnt cause it to break down,but you will lose power and not run too good.whats wrong,cant you just tighten it back up?

Answer 7

No it won't. But it will make the engine miss fire like the dickens.

Answer 8

yes - it would misfire and not run right - possibly causing you to break down

Answer 9

No
