[Mk2] [Turbo] Where Has the Power Gone????????????

[platmatt8]

It`s coming on boost as normal, starting to think it`s a fueling issue

[TUBBY-DEUCE]

mine was coming on boost with the timing out, but because the engine couldnt breath it wernt going nowere, lol.
i wouldnt be driving it too much , get it looked at asap

[platmatt8]

so which way is the cheapest< timing check or afm replacement?

[TUBBY-DEUCE]

id get someone to check your timing and your cam belt, then if all is well look into other things ie; fueling and afm

[platmatt8]

well i think i`ve found the problem it`s the afm, between terminals vs - e2 i should get a reading between 200ohms and 400ohms i get about .5kohms.

I can get the correct resistance value if i bang the afm a few time then i get a value off around 399ohms which is just in the limits. But a few more bangs and i lose it again.

sooo.........

mite be a daft question but have you reset the ecu?
if im out and about i mite come over and let you try my afm threw the week if you stil need one.

[platmatt8]

Well if you out and about that would be spot on, i think i`m getting one anyway because off the situation of having to bang it to get a good reading. pretty sure this is the problem.

Never tried resetting the ecu because never got any fault codes on the diagnostic.

Blocked exhaust?

Mine wouldn't make boost when I had a blocked exhaust.
