Lt1 problems Sign In

I have a 94 camaro z28 LT1 with about 100,000 miles on it that I replaced the timing chain, spark plugs and wires, knock sensors, 2 temperature sending units, air pump, AC compressor, thermostat, and my exhaust gaskets. I got everything back together and its alot better than it was but its still lacking power and now my gauges are telling me the engine is running hot when it isnt. Also I think my timing is still a little off so I'm guessing my ecm may have problems but I dont want to spend the money on that without knowing if thats my problem. Please help. Thanks

I'd start with a good code reading then check for exhaust restrictions with a lack of power issue,

I thought my ECU was messed up so I pulled it. I took out the knock sensor module in the box and it runs better but still no power. I have been running diagnostics after everything I've done, I'll check the exhaust next, thanks for the help
