Hi everyone.......My car was running fine when all of a sudden it started to drive really rough. When ever i stopped it was almost stalling and accelerating in any gear made it kangeroo down the road!! i am just about to go and check all the pipes under the plastic cover, and also the boost hoses for any leaks. Any tips would be greatly appreciated. Thanks.

Stuey,

What Z have you got?

If it's a Japanese spec then are you using super unleaded fuel(preferably Shell Optimax)

That could be the cause.

Cheers,

F.T.

Its a 91 uk spec. I'm using optimax on it, never had a problem until i put a APEXi filter on. Since then i've already had 1 air mass sensor go, but i thought it was just cos of the fact it was over winter and that the unit was old. Now the first time the car is driven properly in the wet for a while, 4 weeks since the new unit was put on,and i'm getting error code 12 again!!! What the f**king hell is going on?????
