cx-7 and problems

check the Check Engine Light thread. I believe 3 folks have reported a check engine light caused by a "leaky detection pump" in the exhaust system, and 2 have reported a check engine light caused by a loose gas cap.

Got 4,500 on my CX-7. Had an issue early with the check engine light, details in that thread. Fixed quickly, no other issues at all.
Got about 1600 miles on mine... half of those were put on by the dealer (kinda sucks but I got a decent deal). No problems so far, except I found the remote start doesn't work - it'll start the sequence but the car never starts. I'll ask about it the next time I'm at the dealer.

Remote start
The salesman showed me how they screwed up on that remote start...gotta get new chips for it or something...it's wrong. Dealer should know it needs to be redone. Good luck! If you hold it in the car it will work.....hee, hee.

You are right. But here's the rub. Basically this is a MSP6 motor. It has the same (9.5-1) compression ratio. Mazda recommends 93 octane for the MSP6, and warns of power loss (ECU induced) if a lower octane is used.
What's the difference that would allow for a lower octane, or has Mazda misstated the recommended octane for the CX-7.
See the MAZDAUSA page for MS6

I just looked at the MAZDAUSA site, and the recommendation is 91 octane there for the CX-7. The MSP6 spec page recommends 93, with an asterisk footnote warning that 91 and 89 can be used mut may aggect performance.
Like I said, it doesn't make sense to me.

I believe I read somewhere that one of the reasons for the CX-7 having ~30 fewer HP than the MS6 is that it's tuned to run on 91 octane fuel. Compression may be the same, but the boost is lower on the CX-7, I believe.
Anyway, the manual clearly states the it requires a 91 octane so a 92 should be fine. If you get a lot of detonation, I'd recommend taking the car to the dealer. Also, make sure to buy gas from reputable gas stations.
