Plugs, rotor arm, cap and leads are new. The coil was checked with a multimeter as instructed in the Haynes manual.
I only have one of the old plugs which probably doesn't help much, but that's how the plug looks:
Looks fine to me, I'm no mechanic though.
We've had pretty good weather here for the last month or so, so good that I'm running summer tires now. All of the wheel stuff is checked out, pressures are set, rims are straight, tires are brand new.
The brakes shouldn't be dragging as the wheels spun freely when I had the tire replcement done. My handbrake is pretty weak, doesn't hold the car if it isn't engaged to the last possible spot on the ratcheting mechanism. One click down and it rolls freely. But that's not the problem here, just saying that it surely doesn't drag.
The bearings I haven't checked, I don't have any whining or anything like this though. Only whine I have is from the gearbox, in 1st gear and then rapidly slowing down from a high speed.
My regular commute and the trips I have taken were usually on flat roads with moderate traffic. I hardly ever get in traffic jams, I either try to avoid them or get out of them quickly.
The injectors are also a mystery. I haven't had them checked. My mechanic told me that this isn't needed but I don't know really. Should I get them checked out?
What about the oxygen sensor on the exhaust?
