Having problems with your 2003 Jeep Grand Cherokee ?
2003 Jeep Grand Cherokee The fault code 302 reads from the ODB. the mechanic thinks this could be blown head gasket or cracked cylinder head costs $$$ to repair. However at same time A/C ceased to work and cruise control stopped working a few weeks earlier. Ciould this be a vacuum leak problem?
Trouble Code: P0302
Does't sound like a cracked head to me I would take a look at all the vaccum lines.Also check the intake manifold and the egr system.
