Hi all, just purchased a 94 type ra just over a week ago, since whenever I've been driving it - I run it on Tesco 99ron & OB - it keeps hesitating whenever I accelerate, then leaps forward, usually around town, on fast roads it's fine and it doesn't seem to make a difference whether the tank is full or low and it's a lot worse in the morning. I have now added an induction kit and downpipe, but it hasn't made any difference - - any ideas??

 

Hi m8 had the same problem on my my95 turned out to be the induction kit put std airbox back with k&n panal filter car runs fine. Also do you have a boost gauge because mine was overboosting and alsorts with the induction kit.

 

It was doing the same thing before I fitted the induction kit....

 

My RA was fine until i fitted induction kit and induction pipe now's its overboosting and allsorts..must be an RA thing

 

Coil packs or plugs

 

Coil packs - it has been suggested that perhaps it's the petrol pump...

 

Check the plugs and coil packs, do you know when the plugs were last changed? from memory I think they need to be gapped at .7 I'm sure someone will correct me if I'm wrong.

Are you running a DV and what type?

I'll send you a PM

 

I've been told it's unlikely to be the plugs or coil packs as the problem would be all the time, not just intermittently. And I was told by the previous owner that it hasn't been serviced since he brought it into the country last April.
I've got a Bailey VTA....sounds totally different on this car lol

 

This sounds like the symptons that Kevwrx95 had then, can you beg steel or borrow a ICV as they are over £270 from subaru.

Just trying to find the thread........back in five

 

Here you go.....

Couldn't get Tesco 99 ron last night, so had to put Optimax in with no Octane boost - this morning it's running fine, no hopping or skipping or hesitating!! So I might try another tankful when this one runs out and see what happens, if it runs fine then I'm staying with Optimax lol
