Misfiring
Hi,
I have a 1988, 1.9 DG Auto that is misfiring and running roughly.
I had some new spark plugs lying around and fitted them with no change. The plug leads, whilst not new are in good condition. Van is starting fine, even from cold.
Anything to suggest to help?
Thanks in advance.
Jim

Re: Misfiring
Rotor arm and dissy cap ?
Also check for induction air leaks , a perished vac pipe end can cause all sorts of mis fires

Re: Misfiring
does it do it when cold or when cold and hot?
if it's been left parked up it could just be damp, have you tried some wd40?

Hi.
It misfires from cold, and still does it when engine has warmed up.
It's been misfiring for a few weeks but this is the first time I've had a chance to look it
Cheers

Re: Misfiring
Going to test the coil today to hopefully rule it out
If the engine is starting OK, does that mean the ignition amplifier is working?

Re: Misfiring
Just cured mine by changing the coil. Had a crack in the nose insulation and the spark was occasionally tracking along it to earth (found in the dark).
Also you may think your leads are good, but if you have metal shrouds on the plug ends they can cause problems, and can safely be removed.

When testing the coil, should the ignition be on or it doesn't matter?

Re: Misfiring
Hi,
Just an update, still not fixed.
The coil tests OK.
Can't see any vac leaks.
I've changed rotor arm, distributor cap, plugs and plug leads to rule them out.
Engines starts straightway when cold, but is a pig to start from hot, does this point to anything in particular?
Cheers again.

Re: Misfiring
You can’t "see" vac leaks , you can only hear them .....
