What would cause a lean mixture?
Ok, before I install my new t-belt it was running at around 11.2 but after I change my t-belt, it seem to be running at around 12.3 during WOT. I don't think it's the timing belt causing that.
First thing before timing belt is turbo upgrade.
Second is timing belt change.
Third is I couldn't find a cone filter so I bought K&N filter and just cover up the MAF adapter.
Would one of those event cause the lean mixture?
