I changed a few sensors on my van and then had no power so I left one new sensor in and put one of the old ones back in then unpluged the mass air flow sensor and the van had power again while the check engine light went off then back on again. Then the other day I had black carbon coming out of the tailpipe with a very strong gas smell and the gas needle dropped. Any ideas please help
