#45 of 212 LOSING MY MPG!! '02 Chevy 1500 5.3 by jcruzmc Feb 08, 2008 (11:52 am)
I have a '02 Chevy 1500 5.3 liter with 55k miles. I put on a K&N air filter and tornado about 3 years ago and was consistanty getting 17.5+ mpg. During the last 7 months, mpg has been steadlily, consistantly going down. My last tank was 13.5 mpg for the same kind of driving as usual. The air filter is clean, I replaced the fuel filter, the tire pres is good, the spark plugs were replaced (they were in good condition), and I get no indications (check engine light, eng perform.) that something is wrong. I use premium gas because I found that I got more mpg per dollar by doing so. Also, in the Chilton maint book it says that a bad EGR valve could cause poor mpg. The thing is that my eng doesn't have one even though my VIN # (with a "T" in it) indicates it should (the chevy maint people can't explain it). The decrease in mpg seems to have started when I put on all terrain tires. The psi on these tires are 45 (compared to 35psi stock tires) and they are about the same in diameter. If it were the tires, wouldn't I see the difference instantly and not over time? The Chilton book suggests checking the exhaust and emissions systems. How do I do that? Any other suggestions??
#46 of 212 2000 Chev p/u starting problems by chevyjoe Feb 09, 2008 (4:13 pm)
Own two 2000 Chev pickups. One of them will sometimes start with a "metal clanging" sound, and the battery gauge will be low. Now when it does this, the key will not turn the truck off . . . it finally dies. This noise problem/low charge problem is not happening every time truck is started, but seems to be getting worse.   The other 2000 chev p/u would not start, so bought a new battery, started, but the battery charging gauge is low. Help, pls.

Replying to: bowtieheadache (Mar 08, 2008 4:27 pm) it is common for the gage cluster to cause simmilar problems i noticed with mine the gages didn't move a fews seconds after it started for a month before it started draining the battery the bad news is it cost $500 dollar for the computerized gage cluster i did a lot of research on line and the gage cluster was a common problem with 2001-2003 bowties Replies to this message: bowtieheadache (Mar 09, 2008 6:19 am)

Replying to: pipefittterr (Mar 08, 2008 8:09 pm) Thanks for the tip.I am going to replace the guage cluster.Just to be thorough,I am going to have the starter and alt rebuilt.It just seems weird that I drove it all morning around town yesterday,and then it did it in the afternoon,thus the "dead at random"  ??did you go to a dealer for the new cluster,was it OEM or aftermarket?
#53 of 212 Chevy 2500HD will not start by bandera1 Mar 19, 2008 (11:47 am)
I have a 2001 Silverado 2500HD with a new battery but intermittently will not start. No click, hum or nothing. It seems like the security interlocks are not all releasing; if this is possible. Sometimes I reset the remote, slam a door, lock/unlock a door or something similar and the thing will start. It may go days starting OK, but then it won't. Any ideas?
