Engine going south

mardi 13 mai 2014

Been having some rough idle. Not bad but enough to think coils, wires and plugs. They have about 14k on them. So I bought them myself and took them in. Two coils bad per Mazda. So I replaced them all, wires and plugs too. Didn't want to go back in 4 months when they fouled.



Also been having problems starting when hot, especially when using AC. In a minute or two its starts right up. Happened four or five times.



Had compression test due to this, numbers are Rotor 1 5.7/6.1/5.7 Rotor 2 5.8/5.8/5.5. No other numbers on print out. When I asked they said "Typically 250 rpm". Typically, but who knows. Not them I suspect.



Coils fixed idle. Still with hot start problems. Are you guys in agreement the motor is on its way out? My understanding from here mostly is that 5s are marginal passing. They did say, those aren't great numbers but they pass. So I'm thinking could last 1 year, could last 2 months, who knows.



Its a 2005. On second engine. This one has about 35K on it. Its worth 6,500 to 7K. Rebuild engine pushing 5K for engine and install. Its 9 years old. Needs tires soon too. May be time to move on. I'm sick.
