^ Yea. How did you diagnose that the cam was worn out?
Also with the compression, if you only pulled 1 spark plug at a time the compression can be significantly lower than if you pulled all 8... piston speed can greatly influence your results. And on that same note how old is your battery, starter and cables?
IMO, if you have 130psi +/- 5ish psi across all cylinders your engine is fine.
I only pulled one spark plug at a time.
When I got this truck it drove fine for about 10 hours back from ND. Then it had trouble starting randomly, but would crank? Once started the engine would run fine, but then the truck began to have more trouble starting and then the engine started to idle rough. Now the engine starts fine, but when I give it gas it stalls out. I cannot go above 10 miles per/hr and when I stop, it basically shakes, stalls, and eventually shuts off (Sometimes backfires). If I push the pedal to accelerate at a stop sign, it will stall out, but always starts up. This is a TBI engine
Parts I replaced so far:
front upper and lower ball joints, new front tie rods, new pitman arm, idler arm, stabilizer links
New front lug bolts
Front Differential fluid change
Oil Pump Replacement
Oil pan gasket replacement and oil pan bolt replacement
New filter and oil
Installed new driver Side Exhaust Manifold - I couldn't get old CO2 out, so I bought a new manifold
EGR Valve
Replaced O2 Sensor
Coolant Temperature Sensor
Replace spark plugs & tested wires were getting spark with tester
Replaced fuel pump - tested gas pressure
Replaced distributor cap and rotor and checked timing was at 0 degrees with a timing light
Replaced Throttle Position Sensor (TPS)
Idle Air Control valve
Rebuilt and cleaned Throttle body with rebuild kit
I can see the injectors spraying gas
Replaced fuel filter and ran fuel system cleaner through truck
Replaced front shocks
New front radio speakers
Rewired trailer harness and added harness bracket
Changed driver and passenger side front wheel bearing hubs
Replaced rear shocks
Replaced rear tail light circuit boards and rewired tail light harnesses.
I brought the truck in to have my exhaust welded back together and the mechanic who has been in town for about 60 years said there is no point in fixing the exhaust because the camshaft is bad...stated he could here it and feel it in the way it drove - said it is making a plopping noise. mechanic is an old timer and he said he doesn't do engine rebuilding any longer because he is to old. I tested compression and figured I could remove the camshaft and measure it and look at the top end as well. THE TBI is now covered in black and the last code I got was 45 Rich Exhaust. It does backfire out of exhaust, but half my exhaust is cut off...
