Hey i am selling my 1988 rx7 gxl as many of you have probably seen and would like to fix this problem. For about the past year i have been having alot of cold start problems. I crank it over for about 20 sec and usally starts then stalls and does this about 3 times, or dont start after the 20 sec then try again and then starts and stalls and has no power untill about 1 to 2 mins of warm up. The first time it starts and i feather the gas to try to keep it running it stalls too. But after i get it running it runs perfect besides back firing. Has about 90 psi cold temp on all faces. Any solutions. Thanks

 

try getting a new water thermo sensor, its located were the top coolant cap its screwed in like a spark plug, it's about 15$
