The other thing, did you change the coil when you changed the distributor? I had a coil start going bad...

fuel pressure is good, not sure about volume though, i dont really have a way to check that... when i did the pump/filter i also upgraded the connectors and wires and checked the harness for any broken wires, cuz i thought that may be an issue in the dry desert air.... i have not checked any program...

I'm seeing 13 psi of boost as well, that's a decent pressure esp. when you add in the fact that this new boosted LT5 features 11.7:1 compression. I question that 11.7:1 report, as IIRC the Direct Injection LT4 with 9.7 psi of boost got only 10.1:1 compression i question this as well - that would be...

sounds like excessive gear backlash or possible knife edging...

up on jacks, trans in neutral, spin the drive shaft back and forth, if the wear is excessive - it will be sloppy - you should only feel a small "dead" spot

if it feels sloppy - get it checked ASAP

im not against the gear being bad - but its the no codes that bothers me, and also suggests its not misfiring but maybe extra fuel - so maybe some sticking injectors?? and the low fuel pressure doesnt sit well with me either, so fuel pump is definitely going in, then i will do the intake gaskets, an...

update - took battery and alternator in - both tested good.... bought a scanner - no codes... still has a pop/miss at idle through the exhaust and reads a steady 40-42psi on fuel..... im doing the fuel pump next, because if memory serves it should be about 55-58 at idle.... may not solve anything, b...

finally got a little time to check things out - charged up a battery and it started up - which raises more questions than answers.... what caused the battery to drain and the truck to die? the alternator has 14.14v output.... it has a pop through the exhaust at idle, and even when idled up, it gets ...

im using 2x8s for the loft area with 2 layers of 5/8 plywood for floors - completely open and nothing load bearing so kinda apples to oranges....

if you can space out the 2x10 @16" OC to meet code, i dont see why it wouldnt work...
