Ok..looking to trace down a high BLM condition on two t-types.
This is whats been done and gone through.
Replaced all vacuum lines, PCV, O2, EGR and gasket, new plenum gaskets, new plugs, replaced MAF with known good one, swapped ECM's and swapped chips, ran MAF rite on throttle body. Engine appears to be really quiet on the drivers side and slight exhuast note on the passenger side. No sounds like a cracked header. Compression all cylinders came up to 170 PSI after 5 cycles.
Tested lines going to ball and cruise control with mity vac and they hold pressure. Cap'd the line to the power booster.
Whew...one car goes to 160 at idle..the other car has been hovering around 145-150. Adding fuel pressure doesnt change it.
Anyone have ideas???
Thx
