Mobil 1 is the chit 200k on my engine just replaced head gasket and you could not fell a lip on the cylinders I am the second owner and new the first owner he ran nothing but Mobil 1
good to know about the knocks the problem was indeed a vac leak the egr valve gasket. Appears one bolt didn't make it through the hole in the gasket so one side fell. So it now has the new knocks and egr gasket. I do have a slight tick on # 5 up top hoping that cleans up with the new oil.
Okay so I replaced my intake gaskets because I had to change knock sensors anyway, and I had some bad leaks . The leaks where odd because I had just replaced the head gaskets and intake gaskets. So as it turns out after changing the knocks and installing new intake gasket I have an intake leak...
Cleaned the map today it helped keep it idling long enough to find the vacuum leaks. so now I will order the knocks and goop the hell out of the intake on assemble. I sure this will cure it they are bad leaks both sides of the intake near the middle.
Psychostang I did get 542&543 (the car was still running)at one point but also got 524 it does exist it may not mean anything but the list I have shows it as low speed fp circuit open. That being said. And I could be wrong but I am pretty should the MAF does not set injector PWM but rather tells...
Yes I believe the o2 can effect the 524 code It's only a guess but I'm thinking the pwm of the injectors would be out of range at idle at normal pressure so they cut the pressure at idle to keep a usable pwm but once the 02 sensor ask for more fuel IE more pwm the low speed circuit opens to...
Well thanks guys I know the inertia switch is fine and I have had the battery dis connected a few times still get the 524, but I'm gonna change the passenger side o2 tomorrow before anything else The car had a blown head gasket for a few miles enough of a leak that i could bubble the coolant...
Okay I've searched Now heres what I've got.
KOEO in this order
524 low speed fuel pump circuit open(pump runs fine)
543 fuel pump circuit open-Battery to PCM ( pump runs fine)
Running I get these
136 Can't find it anywhere!
172 O2 indicates lean This is possible but I have some black plug...
starter
If you had a bad wire it would only be the big red positive attached to the starter If you had a bad ground you would be seeing all sorts of other electrical gremlins related to the engine. Just make sure your battery, is good if it is, save yourself a lot of time and change the...
