I wish i didnt get up at all today. :-(

I drove to macca's and on the way back gave it a wee bit too much throtle.

I have that 4k rpm boost cutting thing. it surge forward once not sure it was a spike... and then just doesnt want to go anymore.

It now revs at just above 0rpm and doesnt quite stall. you cant rev past 3k rpm.

blows a lot of black smoke out the back, change spark plugs which were also black.

could it be the turbo ie like when its dead ?

thanks............ going back to bed now

it sounds like your turbo is blown - black smoke is a sign of this

what happened to me, is that you'd drive the car for a bit, and when you come to a stop, heaps of black smoke will come out the back (like engulfing the car - looks quite funny at a set of lights). It would still boost a bit but i never tried going over 3000rpm.

(this was in a 180sx)

what sort of car is it?

Well a great sign of blown turbos is fins in the cat.... LOL

If theres heaps of smoke then probablly....

Leak in piping will cause everything you mentioned, but heaps of smoke can only be 2 things... 1. Blow by (new motor or rebuild) do a comp test... or 2. Turbine is loose and oil is rushing past and burning through general running which will cause bad idle and your intercooler will be filling with oil....

2 things to do.... pull the pipe off the turbo outlet and see if there is heaps of oil in the pipe. If this is the casue then new turbo time... If not then do a comp test and this will indicate blow by.

Hope its the turbo man cause its easy to replace... Motor rebuilds are not easy or cheap....

      You're making my point for me. 95 is not "premium". It is a "slightly higher octane" version of the basic 91 product. The premium product that they want people to buy (for all the venal corporate reasons of making more profit, and all the possibly specious reasons of it being a "better" fuel with nicer additive packages) is the 98 octane stuff. 95 is the classic middle child. No-one wants it. No-one cares about it. It is just there, occupying a space in the product hierarchy.

      98 and 95 have to meet the same national fuel standards beside the actual RON.  91 has lower standards (which are quite poor really), so 95 is certainly not 91 with some octane booster. It would be an easier argument to claim 98 is just 95 with some octane boosters. Also RON doesn't specify 'quality' in any sense, only the octane number.  Anything different retailers decide or not decide to add to their 95 or 98 is arbitrary and not defined by the RON figure.

      95 is just a scam outright. 98 is the real "premium" with all the best detergents and other additive packages, and at least historically, used to be more dense also. 95 is just 91 bargain basement shit with a little extra octane rating. Of course, there's 91 and there's 91 also. I always (back in the 90s early 2000s) refused to put fuel in from supermarket related fuel chains on the basis that it was nasty half arsed shit imported from Indonesia. Nowadays, I suspect that there is little difference between the nasty half-arsed shit brought in by the "bargain" chains and the nasty half-arsed shit brought in by the big brands, given that most of it is coming from the same SEAsian refineries. Anyway - if there's still anything to that logic, then it would apply to 95 also. 98 is only made in decent refineries and, as I said, is usually the "premium" fuel, both in terms of octane rating and "use this because it's good for your engine because it's got the unicorn jizz in it!".
