Whats going on guys. When I begin to start my vehicle i get a slow crank " like its struggles to start or turn over", and when it does turnover i have to bring up the idle myself by stepping on the gas paddle. If i dont keep on the gas my idle will drop slowly and eventually the car will shut off. once that happens my car will not start unless i step on the gas and keep cranking the car over. after 10 or so times the car will start with a weak idle at the same time i have to keep stepping on the gas. I have just changed my main relay but still getting the same thing. another problem is that when i drive my car after its warmed up the idle jumps from 1 to 2000 rpms for a little while and then it goes away... any bit of information would be greatly appreciated thank you..
