hello again Iposted last week about having no power in my 92 bonnie ive done pretty much everything i can think of to the car plus things sugested here heres a recap the motor has 144 kms since ive had it its always run the same no power under throttle heres the things ive done changed plugs new from gm new cat changed two cracked coil paks had a scan it came up bad cam sensor replaced it new coupler cleaned tb checked maf and cleaned it boost actuater seems to be working checked for vac leak with tbc cant find a leak althoug there seems to be a leak of some kind as the idle is low and rough could some suggest anything thanks in advance

Check the EGR tube for cracks. You also didn't mention changing the air filter

i did change the air filter could you posible show me the tube your talking about

Looks like this. It'* on the drivers side behind the throttle body. You will see one tube come off the rear exhaust manifold, go to this valve, then go to the lower intake manifold under the throttle body.

thanks for the pic i took the egr off cleaned it it seemed to be leaking a bit and it had a cracked gasket i cant here the vac leak anymore but the car runs exactly the same

hello again i realy apprectiate the help my problem has finaly changed im hopeing its a step in the right direction i bouhgt another bonnie (92 se ) changed the maf the old one was brand new but i took a channce it seemed to run a lot better till its warm when i changed the cat could some of the stuff in the old cat be pluging up my muffler when i rev or floor it it blows some black chunks not smoke just chunks thanks agian

I guess that'* possible. did your old cat come apart?
