I have a 94 del sol with an engine swap (vtech) and a few engine mods like air filter aem fuel injecter knew spark plugs and the list goes onn. But my problem is this, when I turn the car on. It idles at around 1200rpm's then if I let it sit for 10 minutes or drive it and then let off the gas, the idle drops to around 500 rpms and the engine starts rocking. Please helpp!!
