check the timing

What codes are you throwing...Your running in limp mode. I was doing the same thing for a while. It's not your timing. It has something to do with either vacume, or wiring. Make sure your knock sensor is plugged in and that plug on the back of your ITM. I put a skunk 2 on mine, and forgot to plug in the sensor on the IKE valve, and I was running in limp.

Don't forget to check your codes. Thats a dead give away.

I'm throwing a code 4 and a code 6

code 4. check crank angle sensor and wiring. check continuity.

check your engine coolant temp sensor with the code 6. check wiring or change sensors.

I am throwing a 1 and 6 in my car. Of course the o2 sensor because there is sapposed to be 2, but I am also throwing a 6. Your car will still run fine with the sensor not working. It should only effect start-up. Mine surges a little, but only until it's warm, but thats also the uberdata being gay.

The crank angle sensor is mostlikely what is causing you to run in limp. Get that fixed, and your problems should be solved, and if thats not the problem hey, atleast its not throwing a CEL anymore . Good Luck man. tell me if any of this helps.

if the crank angle sensor itself is bad, you'll have to get a completely new (used) dizzy. i got one on ebay, but it wasn't as cheap as the guys here were saying it'd be. i had to pay about $45 total with shipping. not that bad for a major car part...
