Per a previous post, I removed my thermostatic vacuum valve that had the EGR plumbed to it and one line from stock motorcraft carb. I then installed a BC Bronco heat shut off valve. I connected the EGR vacuum line and the carb line, started fine, idled fine, after about a mile it started to sputter and died. Very hard starting then. Left it sit for 10 minutes, started up and went another mile and died.
I then installed a "T" into existing vacuum lines off of another port, same result. I then capped both lines, very same result. Pulled fuel line off of carb, removed coil wire to check fuel, seems to work fine. This is a stock 302 with a stock rebuilt motorcraft carb. The thing is, I drove it over 150 miles the day before the change and it never skipped a beat. Any ideas other than going back to the thermostatic vacuum valve?
It almost feels like a fuel issue, but it has to be from the changes I just made. Any ideas are appreciated.
