Problem with engine


I noticed some hesitation while at full throttle yesterday as I was entering onto the interstate and then at 65 mph the car was hesitating and the exhaust had a slight gurgle sound. When I got home I lifted the hood and the engine still had the hesitation noise and I could hear popping as the car was idled. I figure that was probably detonation becuase of lack of fuel or maybe an o2 sensor ar maybe MAF. What do you guys think and would it be safe to drive o the shop or should I have it towed? I drove it home about 10 miles with this problem. I have a procharger kit.

is the kit new?

did you get a tune yet?


I would say if you stay out of boost you should be able to get it to the shop.

Blower


The kit is not new and it was tuned perfectly before yesterday. The air/fuel meter is running on the lean side. It's stays mostly on the lean but when you hit the throttle it raises to stock which is a couple of bars above lean and before yesterday it would stay on the lower end of the rich side.

blower


Yes and it looks like I had a bad spark plug. Easy fix.
Is it safe to run nitrous and a blower? I want to pick up another 100 horses but I want the car to still be streetable.
Thanks,

if your showing lean on your gauges, you might want to go have that checked out. its opkay to run a little fat but its a huge no-no to run a little lean. go get it cherclked out and make sure your tune is on. i wouldnt run a daily driver that close to the edge. just not real safe.
