I have a 2001 s10 4.3 TBI and its running very poorly. I overheated and blew up the old 4.3, and this replacement one has 30k miles on it. When I had the swap done *by a local shop, that also found the motor for me*, it ran great for almost a year, and within the last 3 months its gotten progressively shitty. I was curious how much difference a cold vs warm engine makes on the compression test, so yesterday after the engine was warm, I pulled a plug from each side of the motor (the middle ones that are easy to get to). Checked the compression on those two cylinders - 155lb on both, in my case the difference between hot and cold was 20lb.
Make a chart like this: CYL STATIC COMPR IDLE -RUNNING COMPR - SNAP Cyl 1 150 75 125 Cyl 2 175 80 130 Cyl 3 160 75 120 Cyl 4 160 80 125 7. ANALYSIS: Running compression at idle should be 50-75 psi (about half cranking compression). Snap throttle compression should be about 80% of cranking compression.
I have completed the compression test on my 5.3L. The engine will soon turn over 170,000 miles. The values are Cylinnder, 1st crank, and max: 1-120,190 2-120,200 3-110,200 4-120,200 5-100,200 6-120,195 7-110,200 8-110,200 I don't know what is a "good" value. The Chilton's book states that the minimum allowed is 100psi. 1. ICV and TPS Failure. The idle control valve (“ICV”) and throttle position sensors (“TPS”) are prone to failure on all 4.3 engines, which can result in poor idling, engine stalling, bad acceleration, and other low-rpm running problems.static compression test, running compression test or cylinder leakage test may isolate the sticking valve. However, it is unlikely that any of these tests will isolate the sticking valve if the misfire only occurs while driving at specific conditions. The following suggestions may help determine if a sticking valve is causing this concern:

TEST 2: 'Wet' Engine Compression Test. There is a way to find out if the low/zero compression value you got in TEST 1 is due to a problem in the cylinder's piston rings or in the cylinder's intake/exhaust valves. And it simply involves adding about a tablespoon or two of engine oil to the cylinder with the low compression value. Add a teaspoon of oil to the low cylinder(s) and run the test again. If the readings come up, suspect bad (or sticky) rings. OTOH, if the valves are burnt, do a leak-down test for those. Remember that these motors are ultra-low compression engines to begin with, brand assed new, and the earlier versions were even lower compression.
