hello, again Z masters i just got another 78 280z and was able to start it after it has been sitting for 1 year and a half. the problem is that the motor will not rev past 2500 rpms. idles fine..starts up nice... i've change the air flow meter and still the same . changed the fuel and fuel filter. changed the plugs and wire and cap and rotor. sprayed either and found no leaks . check connections and vacuum hoses.. ...injectors click nicely... i'd appreciate any idea's or answers.. happy V and hope U get luck E. thanks jb

A quick question on a 78' 280z exhaust. Whould an exhaust leak on the manifold cause idle problems? Some coolant spilled on top of the intake manifold while replacing the thermostat. After start-up white smoke from exhaust and unstable idle. A constant clicking sound also began in that area(thermo housing, injector #1 and #2) at idle. The white smoke eventually burned away but the clicking and unstable idle still there..The clicking go's away when i rev the motor up..Also loss of power at the bottom end of the rpm range..Before then the motor ran real well.. Please help me . Thankyou so much.. jb

well, replaced the temp sender..the one with the male plug on the thermostat housing and did get the gage to work. but, when removing the sender i had to use a lot of elbow grease to get it out of the housing ... i drained the coolant just below the upper hose, but when i removed the thermostat a lot of coolant spilled over and on the intake manifold. cleaned it off. replace everything back. started the z and white smoke everywhere and i noticed a tapping sound around the thermostat housing or injector 1 or 2..tap tap tap louder than the rocker arms themselves. eventually the smoke when away but the tapping sound still there with a big loss of power..fixed a problem just to create a problem.. what an idiot.. before all that the z was running real nice and crispy. please help..what have i done?

thanks, for the site.. also got more help from the z-man of washington. thanks z-man. jb
