New Spyder. Now P0300

Wow!

You gentlemen are amazing. I have a 99 5.7 as well and am fighting the p0300 too. I just dropped a grand on a new catalytic converter and Fuel Pressure Regulator, just to be told "Still runs like crap, but at least there's 2 less things to worry about". Thanks a lot, useless local shop. I don't have the mechanical abilities like y'all and definitely don't have the money to throw at this thing. I'm thinking it may be time to part ways, and let someone who can and will fix it take it. You are right... this forum is fantastic.

Jared,

Is your Tahoe running bad all the time or just in certain specific situations? Are you getting the P0300 code every time you drive? Why did the shop suspect a bad fuel pressure regulator?

Jared, you got screwed. I bet they never changed the fuel pressure regulator. It's an integral part of the poppet valve fuel injection system. The parts to make a repair are minimal, the cost is the labor. You should have sprung for the new spyder assembly.

Why was it $1000 for a new cat and the regulator? You should have bought your own cat from Summit or Jegs for $150 and paid maybe an hour labor to an exhaust shop to make repair.

I had a local shop replace the intake gaskets because I didn't have the time. After almost a year the mechanic finally admitted he tried to clean the lifter valley causing debris to flood the oil pan and clog the oil pump intake screen. Needless to say, $5k later my Kon has a new motor and exhaust system.

These days the only people that may have the knowledge to work on our machines would be dealers. They can afford to send techs to training, but dealers are expensive.

Spend all the money you would use at the dealer on some tools and a good scanner. Your mechanic just sounds like a shady guy. You can find a write up for almost everything that could possibly go wrong online.

1100 for Cats and fuel pressure regulator? They tell you to put your hands on the hood and bend over when they gave you that bill?
