Yes A little coolant loss. My injectors are brand new. Does the same with my old injectors.

I have an 87 starion all stock. The car ran fine then one day just started missing sounds like a dead cylinder then it warms up and runs ok still missing every once and a while and idles irradically sometimes even backfiring through the exhaust and through the air filter.The weird thing is soon as you put it to the floor it runs fantastic then when you let off it goes back to running like crap. I have had a couple of starion owners look at it and no one can figure it out. Here is what i have changed and checked so far. new plugs cap rotor aftermarket injectors new clips checked for vacuum leaks new fuel pump set tps voltage per the instructions on this site,changed the cts and isp( think thats what its called) from another car that ran fine. I have owned a few of these cars and never had this kind of problem.
