My friend is hooking up a hydrogen cell to his 98 1.8L primz for a class project. He hooked it up to the PVC vavle and drove it 8 miles and had no problem until he came to a stop. All of sudden the check engine light came it and oil light came on and it started to spudder. He went to take off to get home and he seen a big cloud of smoke or steam. What would cause this? Too much hydrogen gettin burn when he came to a idle or what?
what do you guys think?
