Problem areas for the GM 4.2l Engine. Common missfire Issues for hummer h3, envoys, trailblazer. Water pooled up in cylinder/plug holes. Fixed code p0305. p0300
Dude... You're getting facts mixed up The Hummer h3 uses a 3.5l for 2006 models and a 3.7 for 2007 and newer. (Except the alpha model, which is a v8) They share engines with the Colorado and canyon. NOT the envoy and trailblazer (those have an inline 6, not an inline 5)
@@Brandon-LSX fair enough. The 3.5 is also known for failing valve seats. All the inline 5's are also prone to pcv hose leaks which would also cause p0300. Plus a bunch of other possibilities -injectors -coils Etc
@@edsgarage001 it rolls of the tongue easier and not a lot of in-line 6 American engines it a forgivable slip. Pretty good engines really though cheap ebay turbo get you 500 ponies pretty easy :)
Going outside to do this now.
Thanks bud.
Very informative.Thank you.

Yes you are correct. But the same concept applies to all the inline engines. Very common for water to collect in the same spot.

thank you very much
thank you. I'm having P0301 come up and believe its because of the same reasons you mentioned. Can you confirm that is in fact 5 and not 1? thanks
P0301 is number 1 P0302 is number 2 and so on.
Does this cause traction failure and stab sys issue on hummer H3 ?
I don't think so. I know if you have cam correlation codes it will cause all that traction control errors on GMs. P0011 or p0014
you gotta replace your lower ball joints probably
Is the problem solved after the experiment?
Yes
Iroc LSX I have some of oil in the Spark plug is it another problem?
@@6fshangroup Yes sounds like blow by from piston rings.
Iroc LSX Does it have to be repaired immediately or not?
@@6fshangroup valve cover gasket replacement.
4.2l is a straight 6
