92 Accord EX Bogging Issues
I am still racking my brain on this bogging issue. To date I have:
- Cleaned the EGR ports including those under the EGR valve - what fun.
- Cleaned up EGR and tested operation (off vehicle) with my shop vac. Plunger worked fine.
- Ran tests on the EGR system per Haynes manual.
- No vacuum on hose 16 at idle.
- Battery voltage good at black/yellow wire on control box plug.
- Applied power to harness directly from battery and got a 4 in/vac pull on my vacuum gauge - so EGR vacuum solenoid should be good. Not sure if this is within spec, since none were stated.
- Applied vacuum directly to EGR valve and killed the car. Unfortunately, I do not have an appropriate vacuum puller, but I know my shop vac will kill it.
- Replaced rotor and cap.
- Cracked open master relay and fixed cracked soldering.
I am at loss at this point, even after all my searching and reading. Not sure if I should take a somewhat costly risk and just replace the EGR valve in hope that solves it. Any help would be greatly appreciated.
