Okay, so I’ll start by staying that I bought this bolt-on 2011 gt back in April, and a couple months ago the ac compressor went out (not the worst thing in the world since I live in Seattle). Around that same time I started to have random power loss above 3k rpm. We ended up simply cutting the belt to the ac and let it be dormant, however the power problem continued and got worse, when it had the loss of power it also sounded like the engine was muffled. I took it into ford to have diagnostics run, and it came back that it had a simple misfire and that I needed to change sparks and boots. Did that, same issue. After some forum reading I took it in to have ford change the oil....all the sudden she ran like a rockstar again. Problem is, the dipstick always reads overfilled...a mil or two over the dot. Basically ever since that fixed the issue, every time I start to feel her lag I’ll add half a quart. The thing is, I don’t want to over fill, but I also don’t know why that would fix the issue if it was caused by something else. On a cold start there’s no blue smoke, no sign of oil burning but I’m going through about a quart every 3-4 weeks. I will also mention she just hit 80,000 miles, and I do drive her hard daily. I bought her with a handful of mods, boss mani, airraid intake, bbk throttle, Borla exhaust, and a diablo tune however it did not come with the tuner. Is anyone else having anything similar happen? Anyone know of a good alternative dipstick that will read more accurate? Could it be something else?
