I have a wrx sti ra 1995 and when i corner it judders i thought it was the cv joint but iv change it now and it still doing it

it may be from failing engine mounts allowing the engine to misalign the drive shaft under acceleration and allowing problems in the cv joints or "U" joint

all impreza recommends high ROM.
although 99ron or 100ron is recommended, some uses unleaded for non-turbo and of course notice a sligth defference in performance using high ROM fuel.
in your case is the reverse, means does't need to drain for a change.

I bought a 1995wrx turbo japanese import 260bhp standard,which can only run on v-power 99octane fuel,from scooby clinic in chesterfield (scooby race tune expert mechanics).I was the first person in england to test drive on road (it had not long arrived in the uk & had been put on rolling road a few times),whilst test driving,the turbo boosted normal & then started juddering slightly etc etc,i asked scooby lad "what was that" he wasnt sure(office boy!) & assured me that whatever it was theyre top mechanics would sort it out & do a full service,change the belts etc etc, ...so i bought it,luckily with a 30 day warranty included starting from collecting it.I picked it up about a week later,i got as far as 20mile away(nearly home) & it started juddering again,nothing too serious,so i thought we'll see how we go.next day same again,after 3days it were juddering more visciously,getting worse to the point where i nearly hit the windscreen,i thought its got to be a fuel blockage?.it backfired twice & not long after that packed up & would not start again,i foned scooby clinic & towed car back up to chesterfield.they kept saying "i must of put wrong fuel in",they ended up taking engine out cos head gaskets had blown,engine had died,6-7 wks later they told me to come & collect car with no charge,i was told to run it in for 500 miles steadily,& then take it back,they then changed oil,sparplugs & boosted turbo back up(re-connected it),the boss apologised to me & said if he knew it were like that he would never have sold it at all to anyone,he explained that the engine was carboned up(blocked) they did a nearly full engne re-build free of charge.the boss said if he knew it were blocked up they would of gave it a thrashing to clear the engine.

On both cars, check the fuel pump/guage harness connector under rear seat - the old fuel pump draws too much current and melts the connector causing poor conatct & voltage drop off. Easy to see usually, just cut the two fuel pump wires from either side of the connector and re-join with new crimp connectors, or solder joint.

dude you have to replace your C.V joint[constant velocity joint] let me know if it comes rite ok.
