OK, I have finally gotten my second project car running.... The first time since I've owned the car (purchased 2 1/2 years ago)... (IMG:style_emoticons/default/driving.gif)
Anyway, I've done the following to the '74 2.0l engine: New: Spark plugs and wires Distributor cap Points and condensor Vacuum and fuel hoses Intake runner boots Other: Tested and rebuilt fuel injectors and new seals Timed the engine Adjusted the valves I hooked all vacuum hoses, per AA's diagram. When I started it, it ran at 3000 rpm. I disconnected the AAR and plugged the hoses. I've gotten it down to 1500 rpm, but it was 'hunting'. I soaked the AAR valve overnight and washed out the PCV with carb cleaner. I hooked both back up, but it ran at 3000 rpm again. So my questions are: 1. How do I test the AAR valve to verify it's working? 1a. If I remove it permanently, do I just plug the line to the CSV and wrap the electrical wire (the plastic plug is missing)? 2. I've ordered the TB gasket, do I need to remove the runners before I remove the TB/base? 3. After I remove the TB/base and check for pin holes, anything else to check? 4. Any other suggestions? 4a. BTW, I tried spraying carb cleaner around the TB, injectors, runners, but didn't hear any difference in the engine sound. Also, I researched this subject and found Jack's (championgt1) posting, but there was no resolution, at least in that thread... -- Rob |

Here is an AAR with the hole open about 1/3 at room temp. It's from a 1.8
Like Marty said, hook it up to a battery and see how long it takes to completely close. Mine closed in 1 min 15 sec. I write the time to close on the AAR. Then I can compare to spares etc. When you blow thru it, some air will pass, not to worry. Attached image(s) |
