1987 supra turbo
...okay, at first I was suspecting an IAT, intake air temp sensor, but this technology pre-dates this by a couple of years...so, for a choke we've got a thermal time relay~...maybe this one is bad~
My search brought out a few other things....an oxygen sensor, a TPS and one other could be examined for proper operation~
Okay, you've got two temp sensors, one for the engine temperature and one for coolant temperature...change the engine temperature sensor...it thinks you're runnin' cold and adjusts you rich~
I see we've a EGR temp sensor and a MAF sensor...diagnostics needed to replace these~
