ok so i first want to start this off with saying thank you for the advice i was given befor by others. thanks to that i was able to enjoy my datsun again and ill say i sure missed her. but the reason im back is because of another gremlin in the car. overall she runs great, but... i have to get her warmed up to about 150f degrees until she feels like she really wants to go. to me it sounds like an electrical issue over mechanical again and im wondering if anyone on here might know of and possible things that would cause that. and if anyone might be wondering what happened in the past i had a corrosion problem right at the ecm and that got her on the road after taking care of it.

Have you checked your plugs lately? might be a bit long int he tooth or perhaps leaky valve seals. Could also be any one of a number of electrical connectors that are a bit loose or have a bit of moisture. or the afm needs dialed in, could even have a dead spot.
