One reason I bought this car was because it still had the fuel injection. But now I am getting so frustrated trying to get it to run well, I am considering swapping the FI for carbs. Please help before I switch to carbs!
She runs well cold and hot, but not in-between. She will stall and is very difficult to restart. In fact, I have pushed her out of traffic on several occasions after she stalled at a red light. I wait a couple of minutes and she fires right back up. I have a gunson and have set the CO to 2.5 at idle and 2500 rpm. And again, she runs well once hot. The AAR works. I swapped out the CHT even though the old one tested fine. I am thinking it’s the cold start valve. I disconnected the wire to the CSV last night and reset the CO to 2.5. I went for a ride, came home and shut off the car. Let the gunson calibrate then rechecked the CO. Very lean and wouldn’t run worth a crap. I am thinking I have a leaky CSV. It was leaking when I set the CO and stopped leaking when the car heated up? Can I remove it? How do you plug it? If I just remove the gas lines to it, will it leak air? Is 2.5 a good number for the CO at idle and 2500 rpm? I’d appreciate any help. Please help me keep this car original!! |
