Check for vacuum leaks around the intake. This is the most common cause for these codes.

SOURCE: how to change starter

You have to remove the intake manifold as the starter is just underneath it.
Removing the starter itself is quite easy once you have the manifold off.

Unfortunately, removing the manifold is a right royal pain in the back side!!!.
I can list the removal procedure as per the factory workshop manual if you wish?.
The good news is that you do not need to work under the car,everything is done on top.

P0171

P0174


P0335


P0340

P0385

P0442

P0507

P0601.

all of the above codes seem to have a common cause, they all list a bad ecm (computer) as being a cause, and the last code P0601 points specifically to a bad computer. sorry for the bad news, hope this helps.

My 1996 Cadillac deville northstar is trying to crank but misfires do I need new spark plugs?


Maybe, but can be a lot of things. You need to check for trouble codes (DTCs) using a code reader before trying anything.

I have an 04 pacifica check engine light is on I am getting a code p0302 I replaced the spark plug and coil over plug and injector on that clclinder, what els could be wrong


Could be a different coil that is bad

The PO300 codes do not always tell you
which coil or if a coil is bad

Walk a new coil from cyl to cylinder

Never a need to change an injector & for
the most part spark plugs

Plugs don't fail to fire, they wear & stress the
ignition.

The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. We recommend buying your own scanner and doing it yourself. With a pocket scanner you can check for fault codes to find out why the light came on in the first place. You can clear your cars trouble codes after you replace the malfunctioning sensors.
