Replaced IAC, and TPS. Gauged TPS so it's set right. But while I'm driving any above 15 MPH it'll occasionally give me a rough hoccup, and at highway speeds it's more often and slightly more rough. 93 HO I6 block, everything else is an 89. AW4 and NP241 if it matters.
Breather valve broke off on cat so it was welded shut, my air hose from the airbox to throttlebody is ripped open. Brakes are hard so brake booster might be bad, causing vacuum leak. But this seems more of a crank sensor issue, just wanna make sure.
