turbo removed, stripped and inlet cleaned!

[karls3abo]

if anyone could help it would be great, i recent changed my maf sensor as it was broke, intially after it made such a massive difference i couldnt believe it! then about 2 weeks later it started going into limp mode when hitting 3,000 revs, plugged it into a reader and no codes seem to come up.

it resets itself when i turn the engine off and on but does it again after, the car also feels like it is going to stall at a certain part of the throttle. it kangaroos usually at around 1,000 revs or just over, then as soon as i put a little bit of throttle on its fine,

please could someone help, before i go mad!

Literally no idea mate. Perhaps changing the MAF had no bearing on the limp mode. Sticky VNT? I know you said no error codes have come up but perhaps they reset before you get a chance to read them?

Did you use a genuine MAF?

[karls3abo]

hmm, i think its genuine, although, the one i replaced was a bosch one,, but i dont know if that was the original or not in the first place, i used an ebay company, but the part numbers are the same and everything for the non bosch replacement.

something else that might help is that i took the main pipe that leads the the egr valve off to have a look, and looked inside the butterfly and it was litterally full of black oil. i cleaned out what i could reach with my finger and a piece of kitchen roll, would this be a possible cause???

also the car is a 1999 ahf 110 bph model.

thanks

also something else to add.. every morning, or if its been sat a couple hours it takes about 3 attempts to start, sometimes it judders massively then dies,  and when it does start after putting the throttle on it kicks out a fairly large amount of smoke.

If you replaced it with a bosch one then it is genuine.

Take your EGR valve off and give it a good clean, if you can muster the energy and know how then remove your inlet manifold as well ( the thing that the EGR attaches to) give them a good clean with some Mr muscle. This will probably, if not definitely help your car work better.

Cannot suggest anything else, sorry  mate 

[karls3abo]

no i replaced it with the equivilent non bosch one, but the part number is a match for my car.

and ye i have been wanting to strip all that down and give it a good clean since i bought it, so will do soon as possble and will share my results,

do you know if there is anything to beware of when stripping down the turbo? watched the vids posted on here somewhere and it seems a bit too easy....?

thanks for your help

Stripping down the TURBO? Christ knows mate. I don't even think I'd have the bottle to attempt a turbo change!

[karls3abo]

hmm not to worry, think im going to give it a go when i do the egr and inlet, will post the outcome haha (hopefully a happy ending)

Don't forget pictures 

To get the manifold off is simple...Then I believe it is just the bolts holding the exhaust manifold to the block, obv the turbo is attached to that!
