Hello all,

 

Haven't been on here for a while, did use to vist frequently.

I'm on my 4th truck now, my second silverado 4x4, first was a 1999, now have a 2003 pewter Silverado LT, Z71 4x4 extended cab.

 

I have an ARE cap with the full fiberglass door so I have removed my tailgate, therefore haven't done the tailgate cable upgrade, since my dealer refused to give me the cables since they couldn't do the labor.

 

I have however had a dealer do the stearing linkage recall, to remove the clunking noise, this worked.

 

I do have the drivetrain (freeplay) intermittent clunk, which I understand GM has no fix for yet (and may never) and says it's normal. I have learned to live with this.

 

But I now have what may be an unusual problem that has been appearing for the last month or so? It seems to mostly occure when I am at low speed and turning right? My engine will stall, acts as if it is out of gas, sudden stop? but restarts easily? it will stall multiple times a day(sometimes 4-5), reqardless of wether it's warm or cold.

 

I was wondering if anyone has any thoughts or info on this, also I looked in my owners manual, and can't find any info on where the diagnostic port is on this truck. I assume it would be an OBDII. The local Advanced auto parts down the block from me has the I believe Acutron diagnostics tools you can use free in their parking lot. I don't have a maintenance manual, Clymer/Haynes etc yet since I can't seem to find it anywhere, didn't want to pop for the OEM manual due to the cost, but may have too.

 

I did try search first as well as ask the GM Tech, under various stalling topics, and couldn't find anthing related.

I wanted to try and figure this out on my own, with your help, before resorting to a dealer if possible.

 

Thank you in advance, for any help.

 

OK have been doing some reading here, seems some areas to check are:

(1)Fuel pressure regulator.

(2)EGR valve cleaning?

(3)Mass flow sensor (not sure)

(4)gass pedal return springs

A few on the board have had success with a simple complete cleaning of the throttle body. Guys were finding carbon blocking up the air bleeds, etc...

 

Get some cleaner, and start spraying. It should work. Get everything spotless.

      Trans Cooler Thermostat Valve Body Seals - 2022 10L80

      By Rick_ · Posted

      Does anyone know if the GM 85628205 and 85628208 are interchangeable?   The 85628205 is an assembly of the seals mated to a thin metal shim and the 85628208 appear to be just the rubber seals without being an assembly. The reason I am asking is that I'm installing a PPE Thermal Bypass Valve and it doesn't come with seals.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thanks @newdude, guess I'll keep looking.  Test driving so many trucks that have obvious things broken, I'm thinking "if they couldn't even be bothered to fix the power seat," what else is broken".   Just drove a 2021 where the power seat motor was grinding/binding and wouldn't do anything but make a terrible sound.   An owner that puts dents on the bumper, doesn't fix a seat motor, and had spotty service intervals (along with missing major services) doesn't give me the best of confidence.   Amazed at the number of people that will finance a $60k+ truck, run it into the ground, then trade with a loan balance (every single one had "loan/lien reported" on the CARFAX at the last year of registration).

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck
