HELP! P0300 after engine swap
I have a problem with my 05 TB 4.2 EXT LT (160,000 miles). Here is the short story:
I did an engine swap after the original engine needed a valve job and original block was damaged beyond repair trying to remove broken head bolts.
Got an engine from salvage yard.
Removed head and installed new valves, timing chain kit, water pump, Camshaft sensor, coils, spark plugs, exhaust manifold, cat, 02 sensors, new head bolts and all the gaskets.
Once engine was replaced it started right up but with a P0300 that I cannot figure out how to fix. Flashing check engine. Rough idle and drive. gas smell from tail pipe.
Here is what I have done:
[*]Checked compression - all are 170 - 175 psi[*]Checked fuel pressure - 60 psi[*]Replaced ALL coils and plugs - all have spark.[*]Replaced intake gaskets and made sure that all the bolts were tighten to specification.
I am at a loss here and was looking for direction in fixing the P0300.
Also, P0300 is the only code that is coming up.
Thank you in advance for your help.
