Going to change my plugs and dist. cap and probably rotor on on 740 non turbo, wondering which plugs people have had success with and ones that people have hated. Should i go for a genuine volvo dist. cap, or is there no difference between after market ones? What about spark plug wires? Also is the hall effect sensor on the non-turbo 740's a common thing to stuff up? And, is it hard to pull the whole damned distributor out, or should i get some poor soul to do it for me? It doesn't look easy....The only reason i suspect hall sensor, is i have been having my tacho jumping about for quite a while now, and the other day, when i started it it went broom, brom, brom, dead.....then when i started it again, it was fine. Done it a fair bit in the mornings.....ALSO! (one last question), when i put 98 octane fuel in my ovlov the car runs beautiful, but when i put reg. unleaded (aussie reg unlead. about 92 octane) the car doesn't run so well.....it runs, and appears to perform well, but i can hear it knocking under loads etc. could that mean that my knock sensor is rooted too?!

All i can say about the ovlov's is, thank god they all suffer from the same problems! My parents have a nissan with a 2.4 litre 4 engine, and the stupid thing idles low (as in, 300 rpm, i.e. so VERY nearly stalling) whenever it feels like, and no one knows whats wrong with it!

Anyways, you can't beat a solid ovlov. You know what it is, and you know it'll get you there!

Thanks guys! (oh, and girls....)
