My car has been having a rough time pulling from first gear... I recently changed cam synchronizer and spark plugs drove it at least 2 days no problems... Then stopped at auto zone for oil treatment the next morning I noticed a loss in power... When at a dead stop and then put in 1st gear the Mustang wants to go but then it loses almost all power dang near dies Springs into life and shoots off... I'm thinking dirty maf... I recently changed air filter so maybe big dirt finally clogged engine??? Are there any ideas? Maybe bad ignition wires... Maybe cam synchronizer is off a tooth any help???
