Those are cylinders 1.2.3. and 4. if it is a 4 cylinder then it may be the distributor. I would do a complete tune up plugs,wires,cap. This should fix the problem. Good Luck Tim

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.

Engine shaking while accelerating


check engine light on, code P0300 P0301 P0302 P0303 P0304 THIS ARE ALL MISFIRES, 300 is random, 301 cylinder one 302 cylinder 2 and so on, the evaluation is once apart check the spark plugs condition, if they look ok, replace coils and plugs. if the light is not on, verify it works by turning the ignition to pos 2, if not replace light, if yes, and this here are not the codes, read the codes and re send it, posible bad cylinders, or poor injector.

I would like to know what does this codes means 300 302 303 304 305 and what to do to fix it. I have change the sparks and cables, the coils and the Orings of the ingectors. please help me


P0300 random/ multiple misfire detected
P0302 misfire cylinder #2
P0303 Misfire cylinder #3
P0304 Misfire cylinder #4
P0405 Misfire Cylinder #5

This is pretty common thing, and if you have already changed out the wires, coils, and and plugs then you maybe having trouble with the ECU. The good news is that there are local shops (not as expensive as dealerships) that can either flash or replace your ECU. If you don't have a local shop in your area that does this kind of work, then you will be stuck with the dealership.

Good luck,

P0302,P0303,P0304;P0300 and P1399 found by the code reader on my honda CRV 2001 model.what those are means?


From www.hondasuv.com:

 

The P1399 random misfire along with one or more of these codes: P0301, P0302, P0303, P0304 -- indicates a problem with the valves. The B20 engines in the 1997-2001 CR-Vs are known to have problems with valves tightening and then 'burning'.

So the first question is when was the last time you adjusted the valves? If you don't know or never have, then have them adjusted. Soon...
