hey guys, hopefully someone can help me with this i am stumped.
 
went out to drive my 91 gen 2 the other day, hadnt driven it for a few days and now i have no boost and the car struggles to rev past 4k rpm and feels like its doing it really tough.
boost gauge wont even get up to 0 stays in the negative all the time.
 
any thoughts??
 
checked all the pipework seems fine, i installed a fujitsubo cat back exhaust last week but drove fine with that until i parked it.

AFM dying?   check ECU for fault codes too

You should at least be getting close to zero manifold pressure with a fully open throttle. Seems you must have a restriction in your intake. Take the pipe going into the turbo and see if the compressor spins freely. Or I guess you could have a massive restriction in your exhaust.

Does it rev freely with no load?

Cheers

Ahh yea, as above gen 2 with dodgy AFM cancan make it feel like no power. Happened to my mates car but only occurred every now and then.

Cheers

>.< sorry should of said, has a vipec ecu installed no AFM anymore, MAP all the way :)
 
it revs a little better in neutral with no load but still not normal, ill pull the exhaust off and see if i can see anything.
it feels really restricted but dont know what would do that with it just sitting for 3-4 days, rats living in my exhaust???? lol.

check all your hoses and silicon joins.
 
I had a similar problem and it was because the IC silicon join was almost completely loose, so all boost was lost.
 
otherwise another problem could be the wastegate of your turbo staying open?

Check the linrmes to the map sensor etc. Prolly a split on one of the ends. Happened a few times to me.

ok cool thanks guys, i will check all them tomorrow and see what i can find.

ok bit of an update, checked all the intake piping and IC all seem fine, pulled the factory dump and cat off yesterday and replaced with a Berk one, thanks to Dylan for that :)
 
car still runs like ****. did a ecu reset and fixed a dodgy fuse, same problem.
 
getting no boost and car is really struggling to rev past 4500 rpm, it idles and revs clean, not jerky or lumpy, what could of gone wrong with it sitting for 3 days without driving it??
 
1 thing after another with this car >.<

Did you check your turbo spins freely?
 
Cheers
