So I have a stalling problem only once truck has gotten to operating temperature. It also does a chugging motion and it only does all these things at a stop. I have replaced throttle body and mass air flow sensor and temperature sensor because I once had codes for those. I just tryed using seafoam top engine cleaner today on my intake manifold seems to run alot better but it didnt fix my stalling issue maybe someone experienced this and knows exact fix

 

I also get a oil light when I'm at idle just changed oil and oil filter and did engine flush also meant to add that also

 

if you have the inline 5 cylinder you might want to inspect your VVT valve for clogged or missing screens. pretty common on all 5 cylinder vortec engines
here is a guy doing the replacement

 

Naw nuthin in there I checked yesterday not unless a old screen got hung up somewhere else when I replaced the old 1 but I'm thinking maybe the newer 1 didn't last long cause it was from rockauto probably lasted about 7 months didn't know it could cause stalling and hesitation at idle

 

Did you replace the O2 sensor, as per your DLC codes?

Oh, BTW, still have OE battery terminals?

 

Yeah just couldn't replace the 1 in the exhaust it's pretty seized in so I stopped bothering with it being it just monitors the cat. I believe my problem is the vvt solenoid I bought a off brand not ac delco and I'm guessing this 1 just gave up after a few months last time I buy off brand products

 

And no I never changed the original battery terminals

 

Replace your battery terminals with a nice set. Most people around here seem to get Stingers.
Also make sure your battery has a proper charge, no failed cells, etc. When my battery was faulty my vehicle acted strange-threw codes
Replace camshaft position sensor ACDelco 213-1649 (intake side) ACDelco 213-1557 (exhaust side).
Replace coil on plug packs and spark plugs with AC Delco Iridium, NOTHING else.
Replace air filter.

For the P0141, replace the oxygen sensor in the exhaust manifold. I did this a few months ago and had a hell of a time. I rented the specific socket, only to strip the sensor. That happened even after several days of PB blaster getting sprayed on it. I then took my dremel and removed the body of the sensor, leaving only the rounded head. I took a socket and hammered it down onto the rounded head, and removed it (needed a large cheater bar at the right angle). Hillbilly removal for sure, but it worked without damaging the manifold.

Just throw parts at it and drink beer. Eventually something will happen.

 

Lol thanks for the tip for 02 sensor. I figured out that it was stalling due to a knock off version of vvt solenoid I learned my lesson nomore non acdelco parts. Dammn thing lasted 3 months then malfunctioned everytime truck reached operating temperature
