Question about 1996 Pontiac Grand Am

Please help! 96 grand am misfire...

Ok my car shows PO300 ( random misfire ). I replaced my spark plugs. Then came to realize my exaust is cracked because the clamp broke and the weight of hanging. I patched it with metal car epoxy of some sort then put a sleve and clamps on it. the light still comes on, when driving the car it will loose power and start bogging out but it never fully dies out. im thinking it could be maybe the EGR valve??? Fuel valve??? or maybe the cadillac converter??? who knows i know im 21 and low on $ and this is lame! please help

Sounds like the catalytic converter plugged. Don't continue to drive car till something gets done with this as you can damage the engine by the excessive heat. Do something but remember it is illegal to take these converters off and not replace them, so be careful what you decide to do. good luck with it.

I recently had the same problem with my grand am.The catalytic converter is probably bad and clogged up.I took the exhaust apart underneath the car and hammered a metal pipe thru the converter.This took care of my light problem and the bogging down although this is only a temporary fix.A new converter is 150+ and i didnt have the money either.

2003 acura tl error codes po301 po302 po304 po306 p1399 po300


PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

How to fix codes PO300, PO332, and PO756


the PO300 code is for a random misfire in the engine, PO332 is for the knock sensor and PO756 is for the transmission not shifting or low vacuum.
I think if you fix the random misfire the rest will correct itself or in other words you need to replace the spark plugs and check the disturber cap for damage or carbon cracks and replace the rotor and you might be in business.

I have 03 envoy so 6 cylinder change sparks plugs change oil p0300 GMC code check engine light blinking misfiring


engine misfiring can be either plugs ( changed) HT leads ( broken internally from pulling them off the plugs to do the change)and injector faults. Moving wires around to get to plugs.. If you have individual coil packs for the plugs then check that they have refitted correctly or the wires and connections for them are properly connected .. If all is ok then have a compression test done as low compression shows up as one of the reasons for random / multiple misfires (po300)

2001 grand Cherokee. Code P0300


po300 is a random misfire, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why. If it was a po302 this means its #2 cylinder thats misfiring,ETC, But po300 could be any one of the cylinders. check plugs, wires, fuel injectors, Etc. Good-Day!

Random misfire on all cyliner a po300 code pops up in the scanner...


It sounds like the coil is breaking down or the cam sensor may be at fault for the misfiring. Use an inline tester and connect from the coil tower to the spark plug wire to check for a good steady fire. Do this on all coil wires to spark plugs. The best time to do this is at night so you can see it fire. You may want to remove the spark plugs and inspect them for a fouling condition. If all is well then look at the cam sensor for the problem. Hope this will help you.

The PO300 code is random/multiple cylinder misfire detected. Sinsc you have the code PO302, that means that cylinder 2 is the one misfiring, usually a bad coil pack, or spark plug.

Random misfires are some of the trickiest problems to solve, usually an ignition system problem a bad or weak coil pack or possibly a spark plug wire. If not the ignition system then surely a clogged injector.
