Today I put in new spark plugs/wires and new fuel injectors (refurbed, 19lb)..oh and a new fuel filter.
Everything went fine... runs good.
However, I'm still hearing pinging/rattling under two conditions
1: Modertly low throttle I'll hear faint pinging, lets up the second I lift off the throttle
2: Punching it... once I'm flooring it, getting to about 80 it pings/rattles quite loudly. Sounds like it's coming from the left side which would include that fuel rail AND the power steering pump.
I've replaced the tensioner, idler and the a/c coil/pulley and clutch. I do notice a lot of end slap in the power steering pulley.
So my only ideas about what's the pinging:
1: bad power steering pump
2: actual lean condition so it's real pinging (fuel pressure checks out at idle & key off)
3: timing chain rattle
The car only has 83k miles, so I don't see where a timing chain could be part of it.
Thoughts and ideas welcome!
