Pinto Misfire

[Pintogogo]

My 2.0 pinto tends to misfire when revs drop when changing gear, car picks up and accelerates well but misfire annoying, replaced plugs leads etc, has anyone had similar

Cheers - harry

did you check dizzy cap and rotor arm and leads incase they shorting out?

[Pintogogo]

never had dizzy cap off, thanks will look at that, if it has points/condenser will a electronic dizzy replacement make much difference

[Guest 2b cruising]

As far as longevity and reliability a big YES.

if you buy accuspark kit you get new dizzy + cap + leads + plugs + coil sorted

plugs leads cap and rotor arm are not very expensive. and drop in a accuspark module. set timing once.

 

never touch that again

How come you never have to do timing again is it fixed the acuspark

Yes without a doubt, better starting and smoother running, virtually "fit and forget"

 

I fitted one of these to my Beauford 4 years ago and haven't had the cap off since.

I 100% agree fit an accuspark or similar unit if you are still running points but I'm not sure a misfire when off load as the revs drop is going to be spark related.

 

Can you describe the misfire in more detail. Popping/banging in the exhaust? Juddering through the transmission? Engine rocking violently? Does it do it if you change gear at 3000 rpm, 4000, 6000? Does the engine idle steadily? What sort of dizzy are you running? Particularly what vacuum connection/connections does the dizzy have?

Engine idles steadily and it is a 'popping' in the exhaust (like a backfire), when the revs are dropped and then the accelerator pressed the engine pops for a second before picking up, I'm at work but i'll check vacuum connections and dizzy when i get home.

Thanks for your help it is much appreciated

I have same problem and i have new accuspark kit on..i have vacum in every inlet on bike carbs..at every chance i drop the gear to hear poping and banging in the exhaust..was told that pinto does that a bit..my s7 done it too..

But when i give her beans she goes and not popping or banging..love it

Once fitted and set it never wears out like points.

So no checking ..No readjusting

Fit and forget.

Thanks for the help guys, it is much appreciated, I've been looking at accuspark kits on ebay (dizzy, coil, leads n plugs) and was wondering will one kit fit all as I think my dizzy is a Motorcraft one ( black dizzy cap, spring contact on top of black rotor arm), or are there kits to replace Bosch and Motorcraft separately?

Popping and banging in the exhaust on over run and hesitation on pick sounds more like a fuelling issue to me. Have you had your carb/s set up properly or are you running on a best guestimate?

[jaimo]

My pops etc on over run does sound good but lacks power will get it set up when new engine in but might put the bike carbs on now too
