Missing and backfire

BADCSL · 16-12-2012, 08:24 AM

Hi guys.

I am having a problem with my csl as it is missing and backfiring with no power.
The car has not been used much this year and recently when I wanted to drive it, it began to idle unevenly and miss.

I began to think that it was the fuel that lost its power, I then added fresh fuel without draining the old. The problem did minimize but it's still doing the same.

I also noticed that there is a ticking noise when it idles. Sounds like a injector pulsating.

Any ideas guys that can assist me.

Thanks

Head gasket I would imagine?

Or maybe just the lambda

Have you had the faults read? That and a compression check should find the culprit.

Would agree with Shimmy but would have to see car to confirm

I'd lay money on head gasket.

Hi,

Calculated Guess at COP issue,
more so if they are Bremi's.

Did you take the plugs out and
see what they were like ?

Badly Fouled plugs suggests Coils
or, water droplets and its pointing
to H/G as others have suggested.

Slim chance of TPS ?

Regards,

The Gorilla.

will wait for the outcome.

wouldnt a damaged head gasket will cause it to heat up.

no overheating experienced

No as S54 gasket goes between cylinders and not the water jacket so you get pinging and loss of power first

Don't worry. H/G not a big job unless it's driven too far and damaged head.
