tinto99 First came on last week when my girlfriend took it a couple of blocks, noticed the light as well as car almost stalling, before immediately coming back home. Not driven since then. Today, I check under the hood, all vacuum tubes look to be in place (including the after-market cruise control ones that tripped the CEL 6 yrs ago). Also, gas cap tightened properly. One problem I noticed was the blown 30A fan fuse. Replaced it, but CEL still on. Besides O2 and plugs, any other ideas? I don't think 7th gens have MAF sensor, correct? Thanks in advance.
