I'm chasing down what I think is either a vacuum leak or exhaust restriction. When I push the throttle, I get sputtering and misfires unless I floor it above 2k rpm, then it will go. After I let off, we're back to limping along. When the CEL comes on, everything drives just fine, I just get ~10mpg.
I've done a visual/"wiggle" check on vacuum lines and haven't found anything amiss. The only two places that might have an issue are the line going into the heater valve (looks like a tape fix there) and the cruise control line going to the vac canister in the bumper (which I fixed with no issue till now).
I multimetered the CTS, MAP, and IAC and they all checked out. I also checked the TPS and it is getting power to pin 1 but no response from pin 2.
So besides getting a vacuum gauge to properly test for leaks and replacing the TPS, what else should I be looking for?
Thanks in advance!
