Only other thing it could be is no compression, like a burnt valve or bad piston rings-no other possiblilty

    engine needs compression, fuel, spark and say it has spark, is soaked with fuel (so I assume you changed the plug for a new on, hence you said new plug)-say it has 140 PSI must have are missing something. Check it again, does it 'have' spark? If the plug is 'wet', is the 'new' injector defective? How did you test compression-were all plugs removed, throttle completely open, are readings before or after you sprayed oil into the cylinders to see if the compression was different from the top end readings?
    There has to e a reason why it is not running, I want to help.

97 chevy tahoe running rough update....

code P0303 is a misfire code for cylinder # 3, Possible spark plug, wire/coil or injector problem. P0141, bank1 sensor2, is the upstream oxygen sensor, this code may have been set by the misfire of Cyl #3, the lean condition is being cause by the misfire. Fix the misfire and clear the codes and P0141 should not return. If the vehicle is equipped with Coil over plug system try swapping the coil with any one of the others, test drive and if the misfire code changes to another P0300 code ( P0301, P0302, P0304 etc...) the coil has failed and will need to be replaced.

It has a misfire ,we changed the plugs and the coil pack and wires still has a misfire what else could it be

Gas or compression. Check the injector circuit on 1 and 3. Are they pulsing, to put gas in the cylinders? Do a compression test to rule out loss of compression as cause for the misfire.
Kind of odd it would be 1 and 3, but that is one right after the other in the firing order of, you have a single coil? So you have a distributor-examine closely the distributor cap and rotor if those were not changed too, with the plugs and wires. Look for damage, little black tracks that indicate shorting of the spark, maybe damage at the electrode tips on the inside of cap on 1 and 3 plug wire towers. Most people change the cap and rotor when doing the plugs and plug wires.
Just a possibility also, that the injector ground wires for 1 and 3 might share the same ground. That is to say, they might splice together before going to the computer where the computer internally grounds injector circuits to cause pulsing. Well, those are my thoughts, good luck. And let me know what you find, always interested.

Cylinders 1 and 3 misfiring on 2.4 Liter 97 chevy malibu

code p 0300 is random/ multiple cylinders ----misfires detected ===causes ---spark plugs ---HT lead/s---injector/s---ignition coil/s---low compression---wiring
he has changed a lot for nothing
a 5 year old engine can have a lot wrong with it --so new out of a crate is no guarantee
most misfires are from injector problems
it could be a loose valve seat insert so have a compression test done if moving the injectors to new locations doesn't move the misfire

Have a 2002 Chevy Silverado 5.3 4wd. having engin hesitation problems.... service engine light came on...... Changed plugs (Autolite .040 gap) and wires. Problem continued, got worse Had auto parts...

Try swapping the injector on that cylinder with the one next to it and see if the misfire changes to the other cylinder.If it does then you have a plugged or bad injector.It it still stays on that same cylinder then check compression on the number 6 cylinder.Let me know what you find out.Good luck.

Has a 6.0 L with bad misfire under a load and is

Hi Brad,
I ran into the same problem your going thru,
swapped cylinder plug and wire ,and the scan kep telling me it was still seeing the problem on the same cylinder,
smoked it too,nothing made sense!
Until i took the whole fuel rail off carefully not to let the fuel run out all over the engine,Had a white rag folded up and handy,tilted the rail assembly and left the fuel run on the cloth,OMG! the rust that came out of there,
I pulled every injector out of the rail,cleaned the inside of the rail with air pressure and carb cleaner.
Its when I was checking the injectors that I found the culprit,the rust pieces had made it thru the injector but were trapped in the screen of the injector!
I hope this cures your.

I keep getting a P0300 diagnostic code on my 1996 chevy corsica what could be the cause for this

its a random misfire if it had a number at end instead of 0 e.i. 1 that would indicate number 1 cylinder misfired/ but 300 with no other codes can be multi reasons check spark plugs and wires--coils--clogged injectors--fuel filter--fuel pump--bag gas(water) partial clog cat converter these are a few but best to start with plugs &wires
