Hello. I am trying to help a young friend who just bought a 2006 Impala with 130,000 miles.
It has a dead spot - like a 2-second lag when you step on the gas. Not like a hesitation or surge, more like a delay. Not like it is struggling, but just not getting the signal to GO. Happens when starting from dead stop, or trying to go from 20-35 mph. Does not always happen - maybe 25% of the time. Doesn't happen in park.
Replaced gas pedal with attached sending unit - no change, so put old one back in. New MAF sensor installed.
Only engine codes are for emission purge solenoid (fuse keeps blowing).
What should I try next? Clean or replace throttle body?
