'96 Volvo 940 2.3s

Had the plugs out and found them to be in pretty decent nick, however on pot 2 and 3, the screw-on tips were loose to the point on when I pulled the leads off, the tips stayed put.
I screwed them back onto the plugs hoping that it would account for the stumbling over load, but alas, it's still the same.

I'm begining to think MAF or blocked cat as suggested.



Oh, where abouts are you? If you're not a million miles away, you and your Cosworth driving mates should come to the Yorkshire meet, it's always nice to see a Saph, and even these RWD Volvos are getting thin on the ground.

Yes Matt, sooner rather than later... what you upto Saturday?
If its not snowing that is... (which is looking pretty unlikely, as its due to pound it down on Friday)

Hmm, food for thought with the MAF, I'll hit that Volvo breakers up and see how much a 24V MAF is.

Does it have oil?

Oh, and a g/box change isn't too bad if you have a) a car lift and b) assistance. Based on working on a 4+OD 940 (between midnight and about 4am), drop the prop, gear lever out (circlip pliers not essential but *very* useful), wiring off, diconnect clutch pipe, box out. Upper bellhousing bolts are a pain. And the box is heavy.

I can imagine it being a royal pain in the hole on your own on a driveway though.

Hey man, Turbo+ cars were only a North American option on 240s. I don't believe they used that nomenclature past the 1985 240s, the last year for turbo 240s. There were 240 Turbos, and 240 Turbo+, the + denoting an intercooled equipped car (like mine). They were a dealer installed option from 1983 until some point midway in '84, when they were all factory equipped. It allows the boost to be turned up from the stock 6.5 up to 10psi. The 740s and 940s were never marketed as "Turbo +" over here, or anywhere else that I know of, merely "Turbo Intercooler".

Is this car quipped with an M90? We never got those here but they are reputed to be good for well over 300hp. Sorry man, really sucks to change a gearbox out on the driveway, I know.

Awesome you got a volvo - you can look out for me in my grey 240 now! (the orange one isnt done yet!)

By the way, now youve got one, youre hooked!)

Sorry to hear about the missing gear. Are you sure Matt hasn't pinched it as one of his sick little jokes?

Drop a line to the Kevster, he's bound to have something vaguely Volvo gearbox shaped in his tat barn? Especially with his recent found love of the Scandodriftybargewagon.

Hope you get it sorted soon Amigo.

Can you swap the DMF for a 'proper' flywheel from another redblock? Seems a sensible thing to do while you've got to drop the box. I seem to remember a 740 turbo clutch coming with my 240 as a more stout upgrade that would bolt straight up, suggesting good intercompatibilty if the Flywheel bolt pattern is unchanged.

If I want to ditch the DMF I need a 'dogdish' flywheel and a 940TD clutch kit, basically it becomes quite an expensive job and the end result, although it can handle good power, is apparently AWFUL in traffic.

James, I'm hoping I don't need to disturb the flywheel, in an ideal world I would find a like-for-like box and do the swap in an afternoon. Thats the plan anyway, however, I can see it getting out of hand like most automotive things in my life...

if your gonna do all those things to get a different flywheel and clutch in there then the best option still is to contact ttvracing.com and buy a flywheel for a redblock with the volvo 850 pressureplate bolt setup and bolt a volvo 850T5 clutch to it. Those will handle good power and you still have good driveability. But its not cheap, i think a 850 clutch kit is around 300 euro here, and the flywheel was around 250 euro i think.

And the broken 3rd gear on the m90gearbox happens more. If you google it you can probably find somthing about welding somthing around the 3rd gear up to prevent it from breaking. But we never really had problems with them breaking. And my brother has put his m90 to more then 60.000km of pretty hard use.
And a good working m90 gearbox costs around 250 euro over here.

And for the people that wanna know how much pressure the normale volvo high pressure engines use, they use 0.65 bar and the lpt should do 0.3bar. And there once was a tuning kit available that had a 0.8bar wastegate and that was it. With that on the engine they said it would make around 180hp
