When i got mine it was running pretty bad, no power, backfiring. A/F meter had a stuffed sensor. when i replaced that the power problem was fixed and a bit of the backfiring went as well but still idled like crap and backfired a bit. I went and got the injectors balanced, replaced the spark plugs and leads (old ones were x-firing badly) and there was pretty much no backfiring.
I'd suggest doing a compression test also, maybe problem there?

Make sure that convoluted pipe that goes from the meter to the throttle body isnt cracked, car started to run crap a while ago cause it split and unmetered air was entering cant remember if it was backfiring, but definately sounded sick.

Also i've tried a variety of fuels (though not the supermarket fuels yet), the mobil and shell top shelf stuff run ok, but even just plain unleaded works fine. And theres no noticeable power difference with optimax, even if they say otherwise.

The bits and pieces there are easily obtainable, theres several volvo wreckers down melbourne way. To get the injectors done professionally is about $150 so leave that till u have exhausted all the other options.

Hi all:
After replacing the exploded muffler, the coil, the plugs, the coil lead, the dist cap and eventually finding the someone with the right rotor button, and still not fixing the misfire, I finally decided to check the 'cheap and obvious'.
Sure enough, lead no 3 was not working - AU$5 later, with a replacement lead in... no more misfire, and 11l/100k instead of 15l/100k!

Bliss!!

I learned a valuable lesson here; the first mechanic that I too it to (the guy who fitted the new muffler, coil, coil lead and incorrect rotor button), said that he had checked the other leads and they were OK.

Instead of just taking his word for it, I should have spent five minutes checking for myself weeks ago.

OK, oil and filter change this weekend.. who knows, I may even get around to installing the CD player that's been sitting in my bedroom for a few months...

Bye for now...

Good to hear you got it cracked!

cheers
