I just installed a remanufactured engine in my 85 GT. I deleted the smog pump but still have the EGR just capped the vacuum port on the valve. I have an Edelbrock 1406 and stock EGR intake. Installed new headers and clutch. Car has good power under acceleration but when trying to drive under normal traffic conditions car miss fires and bucks. I've tried adjusting the timing and seems to have no effect on problem. I hooked a vacuum line back up to EGR and no effect. I have distributor Vac advance hooked to passenger side port on carb. Car starts and idles fine, just like I said, normal driving it's missing and cutting out but as soon as I give it a little more gas it straightens right out.
I'm thinking of changing step up springs on carb but really don't think this is the issue, any ideas?
Thanks,
Brant
