94 z clone 3.1 5 speed
let me start with what iv done
changed the throttle body with new iac, tps., changed o2 sencer, changed the intake temp sencer, plugs and wires are new.
now the problem
between 15 and 25 or 30 when you let off the gas in ANY GEAR it will give you whiplash. it bucks and surges and goes to hell. at stedy throttle it surges as if you were in a high gear at extremly low rpms. but the engin seems to sound smooth, just the fact of it going up and down about 300 rpm or so. and at any higher speed from say 40 do 75 or so when you let off in 5th or 4th it does the same, just not as violent.
im going to change the fuel filter to see if it changes anything, after that im lost. you guys have any ideas?
and BTW i checked for a vac leak. no vac leak found
