So i bought this hag for 500$ at an auction. The car ran fine. When i was getting gas the coolant hose poped and a lot of coolant went ontop of the engine. After a short while my car died by itself. It takes 10-15 times to get it to start and when it does it sounds like its running on 4 or 5 cylinders. I got 4 codes on the ecm.

p1638 ecm
p1000 ecm
p0128- thermostat stuck open
p0171 lean on bank 1

any ideas what it could be? Stuck injector? Check for coilpacks if they were fried by the coolant? Throttle position sensor? It drove perfect on my way home then when i stopped at the light getting off the freeway it died. Then i used a diesel truck to jump start it because the jag had a dead battery.

 

could be an injector , but more likely a bad o2 sensor , intake gasket , cracked intake manifold .
or if both banks are effected most likely a genral air leak . EGR pipe or PCV/ pipe , blocked fuel filter , bad fuel pump , cat issue .or bad/dirty MAF
if you check your fuel trims you can see if the issue is bank one related only or if bank two is close to triggering a fault code also.
then you will know the next step to search .
it will also need the thermostat fixed to achieve closed loop to recover accurate fuel trims . so your in catch 22 till thats fixed.

BTW p1000 is just a monitor systems check status . it will change to p1111 when the car completes its monitor checks .
it will not complete these with a lean code however. it reverts back to p1000 when you clear the codes .

 

Starts right up. Sounds like a bad coilpack. Checked my plugs. The rear ones were black and the front ones were normal. Two rear are black and the other side as well. The sound only comes from the driver side block.
