Hi i hope someone can help, i have a 92 LS400 that has poor acceleration after warm up ,the problem varies but is always there.this is what i've done so far
TPS replaced / MAS swapped / injectors serviced / filters replaced / faulty 02 sensor replaced / cam timing checked / cats checked / fuel pump ecu bypassed
both the local Lexus dealer & a EFI specialist failed to diagnose the fault even though we were able to reproduce the fault on the dyno with 80rwhp one minute & 160 the next
has anyone got any ideas what too check next? or better still has anyone experienced a similar problem
PLEASE HELP
