The ride quality sucks for an old guy like me. Car bounces and bounds over bumps like a lowrider on hydraulics. Some adjustment might have improved it, but I went to lift the car and the perches seem pretty frozen which caused the spanner to bend.
How much for used coils
The MSP intake manifold has slightly more robust VICS flaps and screws, they didn't fall under the recall Mazda put out back in the day. I know it sounds crazy but I have taken my MSP manifold and the stock DE mani apart when I did a motor swap in one of my MSPs and they do appear slightly different. It's still possible the screws are backing out but unlikely.
Boostr if you need injectors I have a couple extra sets. I don't think injector seals would cause such a large leak but it's worth a shot.
im in the market for a good set of used coilovers. just saying.
I picked up a pair of reman msp front calipers today and one rotor as my driver side caliper has been sticking. gonna get to installing that this week when daylight allows. for the cost of these calipers though i could eat the core and upgrade to mazda 6 brakes SUPER cheap... these cost me $380 cdn with a rotor and brake fluid with core and all that. for some reason i thought they would be way more expensive.
so ill prob get a set of mazda 6 s front brakes in 2017 and upgrade my wife with these msp front brakes.
You can't rule out a base engine issue unless you've also done a leak down test... You may be building sufficient pressure, but can the engine maintain it...there is definitely something going on in cylinders 2 & 3 and its not the engine itself as borne out by my earlier compression check. .
