They told me timing chains stretched purge valve stuck open and camshaft intake and exhaust solenoid a failing internally. Could this all be related to an electrical issue? They said there was a shortage somewhere possibly in the wiring harness .

Runs fine the automatic start was not working . Then today I hit the remote start . The cars starts right up and the check engine light is no longer on. I have not checked the codes again .

the most common issue is stretched timing chains causing most of those codes

the remote starter will not work when there are any current codes set in the computer

can you clear the codes and see what codes come back first

the scary code is the 008 code and the 301 as those codes usually set if the engine oil is clean and full and the timing chain has stretched

The hop looked at it this morning. The car just passed inspection on emissions the check engine light is off. The code p0008 is the only code showing up now. Could this be an electrical issue?

with just the P0008 usually not

with just a P0008 the timing chain is stretched and that will set all those other codes

if the engine oil is clean and full it will need the timing chain kit installed

How much more life can I get out of a stretched timing chain? The job is very costly as the motor has to be dropped.

it will not last much longer and when it jumps it will bend the valves
