tune up

[volvo126]

If your doing the "tune up" don't skip one single thing on rawze's list. Also don't try and piece meal it over time as funds become available the old parts you leave on will compromise the ones you replace. I did the "tune p" 1 1/2 years ago and have not even had one check engine light on in that time. mpg increased instantly .6+ recently I pulled those dpf crossover tubes off and they were spotless inside. This is one of those jobs that you must commit 100% to to get 100% out of it
