A setback....but humorous. Started out to work this am with the new MAP and EGR solenoid in place. Pullin like a freight train, no idle wander.

Topped off with 87 octane and read 17.56 mpg. Happy.

Rolled out. Hit 60 mph.......SES lights up.

Get to work and pulled Codes 32 33 and 42 with a paperclip. Darn. EGR and MAP

Frustrated. Locked keys in truck (1.5 hr ride for wife to bring spares) but a buddy had tools and training and a book and zip zoom door open and keys recovered. So. No angry wife. No paint damage from a coat hanger neither.

Checked connectors on sensors, cleared codes and drove home.

Truck pulling like a train and SES pops on. Damn.

Get home. Install the old MAP and DAMN!!!!

Last night I forgot to reinstall the EGR solenoid wiring harness.

Plugged it in. Put the new MAP back on. Cleared codes. Idles perfect.

I'm guessing tomorrow's ride is a bit less likely to flip the SES on!
