Question

Just bought this car and on the ride home these codes popped up it trembles at low speeds and at idle yet on the interstate runs relatively fine... took it to auto zone to get diagnosed and the said these codes popped up code # p0302 p0202 on a cadillac srx 2004. i am a big fan of d.i.y. but cant find a good video on youtube.Can anyone out there help? i know it is the 2nd cylinder misfire, and fuel injector.

Answer 1

To replace the fuel injector you remove the upper intake there you can access the fuel injector rail. You may not even need a fuel injector, check the connection , these are known to disconnect , there also that possibility that a rodent ate through a wire for the fuel injector

​ Even though this is not a Cadillac check the connection for the fuel injector, if you can easily be disconnected then connection faulty, Rodent can also be a problem as they chew on injector wires
