Re: Engine compression reading and misfiring Posted by SWEDECAR [Email] (#112) [Profile/Gallery] (more from SWEDECAR) on Tue, 10 Apr 2018 08:25:27 In Reply to: Engine compression reading and misfiring, Michel_DDO [Profile/Gallery] , Mon, 9 Apr 2018 20:29:16 Members do not see ads below this line. - Help Keep This Site Online - Signup |
If it is misfiring all the way to work when it happens, it should show misfire count on the Tech 2 scan tool and maybe hone it in for which one cylinder if you leave it with the mechanic.
Even though rare, it could be a fuel injector having issues.
I would also not trust a visual inspection of spark plugs but replace them as well with correct ones when chasing a weird problem.
Hopefully Saab genuine coils were used?
Compression test looks ok to me.
