hello belive it or not my N reg 1.5 nexia returned from the garage today but still had a misfire so i changed the dizy cap leads plugs and rotery arm but guese what still misfired .............................
so after much head scraching swearing and contemplating getting a new ditributer i went back to the garage to bite the bullit while i was there the mechanic decided that it wasnt getting any fuel to cylinder number 2 so had a look behind the top of the engine
there on plaine veiw is 4 electric plugs each with 2 wires going in to them , for the injectors he very simply pushed down on them and we heard a click problem solved no misfire
:-)
apparently these shake loose after a number of miles an takes the fuel away fron the pot so hope this helps it worked for me let us know if it worked for you here is hoping :-)
Remove the cowling on top of the engine block to expose the head, you should be able to see and follow the HT leads.
New spark plugs do not always come pre-gapped. It is always wise to check the gap before installing. The routing of the leads have to be in the same order as they were removed, otherwise cross-firing can occur. Ensure the leads are installed at the distributor in the correct firing order.
check plugs or coil packs..
one or more plugs won't fire
The owners manual says .031, which is right for factory stock plugs. Using Autolite double platinums it's .044. Any less than .040 and your engine will misfire and set the malfunction light.
If bad plugs is causing the misfire. It could also be bad plug wires, a vacuum leak, burnt valve, blown head gasket, etc.
Whats happening is water from your washer jets is leaking and running down your airbox and somehow gettin into the coil pack/leads or plugs, causing the engine to misfire, engine management light will probaly be on the dash. It can be fixed by changin the coil pack but i would recoment tryin to change the spark plugs and leads 1st. This is a common fault with ford fiesta but it shouldn't happen with your year because they were realled 03/53 plates from then on the washer jets at a rubber seal on them to stop this from happning.
Old spark plugs can make a car misfire, run rough, and not fire at all.
Could be coil, leads or plugs. On early models it could also be points. Later models with pointless ignition system problems tend to misfire in all rev ranges
Spark plugs
Bad plugs, wire , coil packs if it has them.
you either did not gap the plugs to spec or you put this wires on wrong
