Im looking to buy an sr swapped s13 with a redtop and he says it has a "cold start issue (starts fine on warm days)" what could this be from?

 

helllp me with this

 

bad tuning, haha.

 

Dude i know your problem. YOU DOUBLE POSTED. STOP IT.

 

Honestly, it could be because of a vaccum leak, timing could be off, distributor, bad starter, like someone said; bad tuning--it could be any number of things. Why would you buy a motor that has problems? Did you do a compression/leak test on the motor, or do you happen to know the results? Compression test will basically tell you the overall health of the motor. You don't even need the motor in the car to be able to tell it's compression.

Let us know what you find out. Good luck.

 

could be a wiring issue, too.
