I took a 2002 chevy blazer here to have dioed, they informed me that they could not do anything untill they changed the spark plugs, OK FINE (I knew the problem was fuel related the plugs just needed to be cleaned, but ok I understand the need for this) After some $300.00 diagnostics & spark plug charge, they informed me the fuel injectors & sender unit needed to be replaced at a cost of $2800.00 or so, we had it towed home. It has not run since then, I replaced the fuel injectors & sender unit, STILL HAVE THE SAME PROBLEM, Today I decided to pull the plugs back out & clean them up & clean out the cylinders, to clear any debri that may have accumulated in the head from all of the cranking I have done trying to start it. The Number 3 spark plug is VERY hard to get out, It took me almost and hour to get it. The stearing collumn it right there in the way. BUT I noticed that this plug did not match all of the others, & was caked with debri, when the others looked virtually new. Obviously these folks changed the ones that were easy to get to & blew off the hard work associated with cylinder No. 3. WRONG DIOGNOSTIC, SPARK PLUGS HALF ASSES, THESE FOLKS ARE SCAM ARTISTS,
Cons: see my story
