Guys I have a 07 suburban ltz it have 164k on it I am have an issue I went to the store and it started running Ile crap and shifting kinda hard and the check engine light came on and flashed and then also the stabilitrac came on too so where do I start I went and had it scanned and it says code 300 I need to mention I just changed my oil pressure sender a few days ago please reply quickly it's my only useable vehicle and I need it to be up and working

 

One more question. Is the nipple that the brake booster hooks up to on the intake supposed to be able to spin? And if not would that vacuum leak cause the issue I'm having?

 

Well not that anyone replied but I took it to a shop and the say it's a stuck afm lifter and I have no comp in 1 cylinder

 

did it run low on oil?


the misfire dtc will disable the traction control and stability systems. So fixing the misfire condition will also fix the stability control light.

 

It uses about 1 quart per 3k and yeah that will be nice to not have to fix more issues I ordered the new lifters and gasket kit for 500 tonight and I'm gonna try and bust it all out next weekend I have a 3 day weekend so I'm staying hopeful

 

make sure you drain and inspect the oil before you tear it all down, also check the camshaft closely. More often than not a set of lifters doesn't fix the entire issue in my experiences.
