Well, I am back and have tabulated my data from the trip. I would run around 200 miles then stop for fuel. (I had a big scare last trip south last year when I had the low fuel warning come on and hit traffic almost the exact same time.) wanted to avoid that this year. At 200 miles I was at about...
I will try that. I have got 60 cents off a gallon for sunoco from price chopper so i will use it but once that is gone will try the shell. I will do anything right now to get me back to the high teens.
You have got to be careful with the delete kits. If you have emissions yearly to go through they will fail you for lack of egr. If you block it and tune it out then they wont know.
Well I reflashed back to stock with the tech 2, I finally did the update for the lbz filter housing from gm, not just adjusting the table. I did the lbz filter right around the time this started happening along with a few other things, so its a matter of ruling things out. I am curious if gm...
I checked my balance rates last night, the highest one was 2.7, fuel filters are brandy new as of last week, before then i would understand the poor mileage. Always run either sunoco or mobil, the 2 stations near to my house. I also run power service each tank.
I last week I did about 70 miles of towing, and about 200 city/highway and thats about it on a tank of fuel. 23 gallons to be exact. By my calculations that is about 12 mpg. What in the hell do think is going on? I imagine i should be doing alot better. My trip down to Virgina beach last summer...
I would not worry. The change in harmonics that go on in an engine to begin with, then throw in a turbo that can change size in split seconds and your bound to rattle some of the cheap azz heat shields along the way.
Hmmmm, ok. as long as its running better then i am happy for you. Thats all i care about. The lbz/lly ecm must be more sensitive to having it replaced because i did my sensor twice, once because i had a new turbo installed, and then because a dam squirell ate the dam harness, and never had the...
The control valve could also be bad. What happens is the valve operates and it gets bound up or goes to far, the sensor then commands a small change and it gets a big one. So its constantly going to run the test trying to find its limits and or the desired position. I wish i caught this before...
Okay, then thats a good sign. Your also probably right about the code, the egr is calc based on maf flow, with the resonator off it will get most of its air through it and not the maf, so the maf reading reduces so much it thinks the egr is overly efficient.
On a side note, when was the last...
Grady, is it possible to get to a dealer. If so, have them hook a tech 2 up to it and go under the special functions to control the turbo. They can command the vain back and forth. This will make sure the vain actuator is working and the unison ring is able to turn. The unison ring is what the...
495 is a cooling fan rpm difference. the other is a coolant temp sensor code.
basically the maf is used to calc the amount of air that has entered the engine to determine if the temp reading is accurate. the pcm has detected an odd reading at the temp sensor.
my bet is the ect sensor is...
