The codes P0300 through P0306 are for misfires of random cylinders or different cylinders. The second code P1456 is for the evaporative fuel tank system having a leak somewhere in the system. Since you are getting random misfires, then I...
Thanks for writing in about your 2000 Chrysler Cirrus. When the coils were removed to replace the spark plugs, they should have been inspected for oil getting on them from a leaking valve cover. The leaking valve cover may leak...
The codes all reference engine misfires. Continued misfires can cause the catalyst to fail and block the exhaust. The past diagnosis you had that the coils could be bad was correct. The coils and plugs should be replaced first and...
Hi there. Your vehicle has a sequential fuel injection system. When the computer detects a fault, it converts to port fuel injection (bank to bank/limp mode). The most likely cause could be an electrical short in the odd bank of...
To answer the question will I pass emissions if P0305 is fixed: if the two other codes are cleared after repairs are done for the P0305 code and they do not come back then you may pass emissions. The code...
Hi there. The first code denotes an air fuel mixture ratio concern; and the second code, P0305, is a misfire detected on cylinder 5. There are several possible causes and both codes could be a related fault. An ignition coil,...
Noise in exhaust systems occurs due to leaks as well as internal failure of the baffles in the muffler or resonator. So, just because there are no leaks, doesn't mean the exhaust system will be noise free. An [engine/exhaust noise...
Hi there. To determine if the injector is not working properly, either you can perform a cylinder cut out test on your injection system or you can swap your injector on cylinder number 5 with another cylinder and see if...
Hi there. The issue that maybe happening is the are fuel injectors that are not firing and there is a vacuum leak on the engine. Possible multiple sensors are not working causing the P2196 and P2198 codes to appear. For...
