would it cause stuttering through the rpm ranges?

 

?

 

this might help

 

Yes, The car will hesitate and not want to rev but will slowly


You have a few options. Get rid of the first cat and check the condition of the main cat. When I bought my 87 it had clogged cats. The first had fallen apart into the second cat.

 

get rid of the main cat. check second cat..drive car..if it is all better then go rb rev 2 no cats just silencer..

 

Not necessarily...

Stuttering through RPM ranges could be lots of things.

Check the resistance on your TPS and make sure it's set to 1K ohms, check your fuel filter and such, your engine and harness grounds...you can check the cat if you want but in my experience with a clogged cat, the car did not hesitate, it just revved reaaaally slowly...

 

ok it might be my cat then it seems like its revs really slow but i havent seen another turbo II rev up before so i dont really know my fd revs up alot faster than my turboII but they are two different cars so camparing the revs between each doesnt really help...thanks for the help

 

my car revved slow too. i took off the turbo and manifold, replaced the gaskets that were destroyed, removed the twin scroll actuator and welded the hole it left, put the assembly back on, and the car felt faster. the boost kicked in a lot earlier, rather than only kicking in at 5100rpm's like it's on roids.
