i have a 87 turbo ii and it does not run right.
seems that it das have misfire problem.i checked compression and its still good(100psi per puff-3 puffs per revolution) changed plugs and wires but when i take off plug wire of trailing coil it seems to make no difference. turbo das not work either(no boost).
it revs up very slow so i tought that i might have cats pluged. dont know what to do next. anyone with any kind of tought what should i do next would be very helpfull. thank you

 

Pulling spark plugs is not going to affect anything.

Is it low on power or is it hesitation?
Change spark plugs...
Change spark plug wires...
Change the fuel filter...
Run some fuel injector cleaner (Redline recommended)...
Adjust your TPS...

its low on power, but today i put a new( good used cat-primary ) and now i have boost(did not have any before). still runing rough though. plugs are new but i'l try new wires and fuel filter and see whats next. thanks for help Ted.

 

You need to do an emissions test soon?&nbsp Just punch out your old cat of all the clogged crap.

If this your main one or the pre-cat?&nbsp You need to really check the pre-cat, as this is usually the culprit that fails and kills your main cat!

i did punch out the first cat and now i have boost but car still run like ****. i took it for a ride and it has a lot of backfiring. when it gets up to 5000 rpm then it starts pulling like its supose to but anything under 5000 it runs like crap. what do u think what could be wrong now ????

 

Try scanning for error codes?
