My car is backfiring. I am currently running Techron thru it to clean the fuel injectors, but I thought I'd ask what else could be causing this.
1. Is the decal valve on a '72 1.7L supposed to just pass air thru at idle, or is there supposed to be a vacuum? 2. How strong in the decal vacuum supposed to be? |
