Do you clean your engine bay?

It seems to be the ones that are looked after and cleaned that go.

Quick update....

Turns out the coil was still almost brand new (after 3 years) which I put down to a quality part, and quality job fitting.

The trouble ended up being the dizzy. The Dizzy was replaced about 4 years ago, after a somewhat dodgy mechanic (no longer in business) hosed down the engine after doing a rego check and service.

The Dizzy got wet, and stopped working. They were liable to replace it (As they broke it) and replace it they did (or so I thought.)

After getting it checked this week after a breakdown, by a very reputable guy, he ended up finding that the Dizzy hadn't been replaced entirely... it had been dismantled, and had the rotor cap and housing replaced, but the hall effect sensor and gearing was original. Turns out the Hall Effect sensor in the side was swapped from the old one (my guy says it was original, so its 14 years old) and if it was compromised by the original damage, it would explain why my car has never been the same since it was replaced.

Anyway, to cut a long story short, he fitted a brand new Dizzy assembly, and HOLY s**t. Its like a new car. Loads more bottom end power, the power steering is as light as a feather, and it takes off like a scalded cat (Which is amazing, since its a 14 year old unmodified EL Fairmont!!) THe only issue now is that its a little jumpy on idle, amost like there is a loose ignition lead. But this is easy to live with until it can be checked tomorrow.

So moral of this story is, find a good local mechanic you can trust.
