Real bad missfire at 3500 to 4000 revs, exhaust very black soot ,

 

Plugs, coilpacks, ignitor module.. cracked piston / ringland... sticky valve

Erm..

David

 

Oil in fmic pipes , fitted new plugs, car really strugleing to go over 3000 revs, turbo does not seem to kick in , Got a mates TDo5 to try that, >> any ideas, cheers,

 

as I said to steven, check all the plugs, if all are oily then turbo oil seals, if just one or two then do a compression test.

Eitherway a compression test might be an idea before swapping turbos.

David

 

David the old plugs were very black dry soot , like its running very rich, after swopping them , the car was just as bad, it seems to be strugleing to go, ??????

 

hope it's not terminal ...

 

Cheers mate >> what ever it is it will mend >>>>>> Just got to find some-one to do it ?? Local scoob garage will not really help cos of the mods on it !!! but someone somewere ??????????? cheers

 

maybe ask wallis/Steven for an 'over the phone' step by step guide to Compression testing?

 

Yep there allready,

 

also check the induction hoses- the hose that comes from the front of the intercooler can leak and cause this problem.

 

Alan, give me a ring tonight if you are no further forward. I can compression test it for you if need be, but it would be easier if your garage did it due to it being next door.

Report back with the results, and we will sort something out.

Wallis and i can do the work for you, as previously discussed, just let me know and we will suggest the best route to solving your problem.

Ive checked all hoses, The turbos not working at 3500 revs like it used to . it does not seem to work at all, the engine just struggles to go, Garage next door was going to swop turbo over tomorrow, Alan,

 

dont suppose turbo chucked something nasty into the block??
debris/vane?
unlikely Im sure.. just clutching at straws (again)

 

Done a compression test this morning it was OK, Now trying to borrow a maff to try that,

 

if it isnt that alan, then let them change the turbo over.

 

Got a Maf (thanks Andy) >> not that,????

 

changed the coil packs >> not that , ?????

 

if you have bigger injectors.....take a look if all of them are stil making good contact

 

I dont suppose you've thought about ECU ?
Might be a try if you can loan one for a short test?

did the turbo get changed? was everything looking normal?

 

I have 550 injectors, not looked there yet, My ecu is apexi power , Thats why we can not use a subaru plug in fault finder, Not swopped turbo yet,

 

Check all pipes to the map sensor, they may be split?

Did you check the injectors by pulling the elctrical connector off, 1 by 1 to see if it makes a difference at idle.

I dont understand why its idling badly if none of the above make any difference.

Do you have the original ecu?

 

You can view all the engine sensor values via the Apexi FC Commander handset if you can borrow one ?
Fuel pressure ?

 

No not got original ecu, I will get injectors checked today, Jonny Gavs coming over on Sunday with his Commander handset , >>> When it misses at 3500 revs plus , Black smoke comes from it , ??????

 

not the injectors,

 

did you check the pipes to the map sensor?

 

At last , Jonny Gav came to York today , checked everything, ended up been the Fuel pressure recolater, big thanks to Jonny >> I was very stuck, and thanks to all above for your ideas, cheers,

 

which reg was it that you were using Alan?

 

Hmm if its an FSE I've got to the point where I am NOT suggesting the use of one, I'd rather map to the oem reg on earlier than MY01 cars than take the risk that the reg may go faulty at some indeterminate point in time.

GB on SX?

 

Go for it mate, or an aeromotive, I'll have one
