My mom has a 2017 cx5 2.5 AWD. Its always had dealer oil changes for its entire life. This time she wanted me to change it for her. I go under the car and remove the little access panel and the 8mm hex plug is stripped so bad I cant remove it. I know how to get it off but it would possibly...
When I had my corksport SRI, I ran very lean (up to +17% LTFTs) due to the air swirling from the cone filter being so close to the MAF sensor. These cars run better fuel trims with cold air intakes. All aftermarket cone filters swirl the air, and with a CAI, the longer length of the tube allows...
Yeah hypertech is a good buy, and you can run it with other mods and it's fine. Biggest change is the AFR under WOT. Before I was very rich at around 10:1, with the hypertech it's now around 12:1.
You won't hyrdolock unless you drive through a pool of water like a foot deep. I live in Washington state where it rains probably 75% of the year, and I don't hyrdolock driving on the freeway with sheets of water getting thrown at me off the back of a semi truck, or driving though mild standing...
I'm assuming the valve cover gasket had a leak and leaked onto the spark plugs and sensors? The parts alone are only about $200 or so. So the labor seems a bit high to me. I could do all that myself in under and hour. $500 for an hour of labor is a lot.
Get a electric tester for 5 bucks at an auto store and test each fuse. You just touch it to each fuse on the little metal part and it it lights up it's good. That most likely the cause.
intake cam would be different. 04-05 2.0's didn't have VVT on the intake cam, but 06+ do. I'm assuming then it's a 2.0? What's the old motor and what's the new motor going in? Both 2.0? or 2.3?
Probably warped the head. If you can do that yourself I'd say go for it. If not, probably cheaper and easier to just get a replacement engine and swap it in.
