Hey guys. Thanks for your past input.

I got back from my honeymoon on Saturday and I bought an OVP relay (or "overload relay") from this site. I have to say, shipping was incredibly fast. I ordered on Monday afternoon and got it on Wednesday afternoon. I recommend the fastlane, and I'll do business here again!

Anyway, yesterday before I installed the new OVP relay and after my car had sat for about 10 days, it refused to start. This is the first time my car has ever done this, but for weeks leading up to yesterday, I had to crank it probably 5 or 6 times in order to get it to fire. And when it did, I would have to rev the engine to get it to keep running.

I was freaking out. I installed the new OVP relay, which was very easy. The car started up just fine on the first crank, which made me happy.

Although my rough idle is drastically improved, it's still noticeably present. Furthermore, my hesitation problem is less consistent (it used to hesitate every time I accellerated starting at under ~2,500 RPM), but when it occurs, it is just as bad as ever.

When I first started the car, the check engine light turned off. Which also made me happy. But then it turned right back on after about 3 minutes of driving.

So, things have improved- the car starts right up on the first try without any effort, and the rough idle is about 50% better. Overall, I'd say the hesitation problem is the same as it always was.

When I took it to the mechanic, they said that I have excellent fuel delivery. So that would rule out the fuel pump relay. They also said I was getting strange readings from the Idle Control Valve. As a reminder, I cleaned my ICV it works very well mechanically, from what I can tell (the valve moves smoothly and freely). So I figured that since the electrical current to the ICV comes through the OVP, the strange readings the mechanic was getting very well could've been due to a bad OVP. So maybe it's a bad ICV still. I have also read about people having bad vacuum hoses going in/out of the ICV, but when I looked, my hoses seemed pretty new. They were very soft and flexible.

I talked to another mechanic and he said it could very well be a vacuum leak. I would probably have to take it to him to figure that out since I would have no idea how to track that down.

What are my next steps? My car was adjusted to pass emissions about a month ago, which drastically increased my rough idle and hesitation. Could this be a tuning or mixture issue? I.e. could it be adjustable?

Thanks so much for your help, everyone. This car is darn near driving me to bankruptcy!!
