Re: Hello from Va
Yea finding the articles helpful. Previous owner installed long tube headers k&n cold air. Removed the AIR components. Crazy exhaust tick from somewhere. Car is running rough. Built the 12 pin adal cable but cant get the drivers to install right to use tunerpro to get some data logs to see whats going on. One day at a time.

Re: Hello from Va
Welcome!
Get under the car and hit the exhaust. I had a bolt fall into the passenger side header (fell down the primaries and got stuck near the collector) that made noise for the longest time before I found it. Hitting the exhaust should let you hear the sound with the car off to narrow down where it is coming from.

Re: Hello from Va
Thanks for the tips. Found two problems. Problem 1 was an easy fix. The header bolts had backed out a little causing a leak. Tightened them up and noise gone. My ac compressor is also bad. Grinding noise on startup then slowly goes away. From what i read an egr valve with no vacuum essentially acts as a blockoff plate. All the AIR/egr piping is gone but that valve is still behind the intake. Will this do until i make a blockoff plate? Loving the car more and more.

Re: Hello from Va
The EGR will throw a code unless it's tuned out. Being the AIR system is off, it might be tuned out already. Depending on your profession, Hawks has a really cheap block of kit that might make it more expensive it make it yourself. Take a look before you burn a bunch of time.

Re: Hello from Va
EGR delete on a 93-95 OBD-1 is hit-or-miss compared to a 96/97 OBD-2. There is a code for the solenoid, which can be defeated by inserting a ~2 kOhm resistor in the harness connector. There is a second code for actual exhaust gas flow, triggered when the PCM cycles the EGR valve and does not see the expected change in intake manifold pressure (MAP). The OBD-1 check does not seem as sensitive as the OBD-2 check. You can delete the EGR, and 50% of the time not get a code. If you do get a code, have EGR tuned out as noted in the post above.
