Hi, I have a '90 Integra, all stock. Car won't start when it's been sitting in the sun, but later in the evening fires right up. Also stutters a bit under light throttle.

Hasn't had a tune up in a long time, but did replace the plugs recently.

I'm new to working on Honda's, but have pulled codes and worked on Ford engines, so should be able to figure it out with a little guidance. Any advice on pulling codes, where to start first etc?

Couldn't get anything to come up in search??

Thanks.

I think it could be your ICM or a relay. Do you have a buddy that has a obd 0 G2 INtegra that you could swap some parts when this problem acts up?

 

Tested relay under hot and cold and it seems to be the problem. Thanks for the help.
