sounds like a tired/dirty iac motor (Idle air control.)

Leaking intake manifold (vacuum )

2010 Silverado after rain or carwash truck dont start, lights on but no crank, i unplug the negative of the battery , wait a min, put it back on, starts fine, sometimes shifts weird, shuttoff than start again, runs fine. could be there a electric part like a modul or relais under the windshield or in the fender what cause this? not happening when its dry. need answers

likely a blown head gasket sucking air and that messes up air/fuel ratio.

Bad gas, bad sensor - take to auto parts store to read codes. Plugged cat.

Check your air filter. Could be fuel pump as well

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Sounds like it's time for a tune up of the ignition system. That would be easiest. If not, have a mechanic check your cylinder compression.

low idle speed...or the need of a tune-up
