I have a d16z6 and when the engine is cold, it idles between 3,000-4,000rpm. When its warm, it idles and purges fast between 1,400-1,600rpm if you know what I mean. The engine also has very bad throttle response and when im going 30mph in 4th gear and when i give it some gas it just bogs, like i will slow down but if i let up on the gas pedal i gain a few mph. I wouldn't have the slightest clue of what the heck the problem is. I really dont have the money to get it fixed by a mechanic. Would anyone know what the problem is?????
