Ok, thanks! i'll take a look I used to be a systems integrator for BMW, Audi, Porsche, Acura, Lamborghini and Mini focusing on diagnostics equipment installation and maintenance actually The last job I did in that field was replacing the BMW Group Tester systems with their new (at the time) ISIS system

thanks. are the clones OK? seems like it's difficult to determine if it's real or a clone on ebay... or amazon... or literally anyone selling one.

What's a good price and place to get a Tech2 anyway?

plugs 1 and 7 were oily wires for 1 and 7 were frayed. replaced plugs and wires. also, noticed some ground wire and fusible link connector corrosion. Might look into getting that fixed before winter.

I started off with a search but most were for GMT800s. Just yesterday my 2009 Silverado 5.3 started throwing P0300 codes. The only real change that's happened recently is it's gotten quite hot out compared to when I got it over the spring. It's always had a bit of a stumble at idle, but nothing serious. I noticed today going up a steep incline under load on the highway, the MIL was flashing. Seems like there's a lot of potential answers for this code as well: Bad spark plugs Bad ignition coils Fuel delivery problems collapsed lifters Crank Variation Relearn. I was wondering if there's a better way to narrow this down without simply throwing parts at it or bringing it to the shop. Any help would be appreciated.

Are the links on the first page working for anyone? It just redirects me back to this thread.
