alright since i have owned this car in november its kinda done this thing where it surges slightly while i am driving steadily down the road, doesent matter the gear and i have been told this is called "hunting" where the computer is trying to find a good mixture. think of light quick jabs on the gass pedal while your driving, it gives that sort of feeling except my foot is steady.

i have cleaned the AFM, there isnt an O2 sensor, it does it at any temp and its just mildly annoying but if i can fix it i will.

i was wondering would a air temp sensor or water temp (before "CHTS" even though its pretty much the same thing) cause this?
what about a minor leak in the exhaust/intake gasket? (very minor)

if not any ideas?

 

those two temp sensors could cause it i expect. you could test them.

and there is no O2 sensor? that sounds like a problem in its self.....

 

in my service manual it even says not all of them had a o2 sensor, theres no hook up for one and theres no bung for it on my car

 

what year car? also the CHTS can very well cause problems mine was bad on my 260ZT and would cause it to flood out every now and then

 

Have you checked the TPS? My Z used to do the same until I adjusted it.

 

that was another question, is the TPS really a TPS or is it just a switch that really doesent do much untill ts fully open or closed?

as for the CHTS question, its a '79 so its the water temp
