Ok so I finally fix all my engine codes then I go and get myself into more trouble
. So here's everything that happened last night I finished class and stopped off to get gas. I have a stock engine, bumped timing 14*, full exhaust, 70mm tb and erg spacer, and a 76mm C&L CAI nothing too extreme. I heard how some guys have been able to run lower octane gas without pinging or knocking so I decided to throw in some super which was 89 octane. Anyway, upon leaving the gas station I pull out go a couple of miles then noticed the temp gauge went all the way through the red and was resting at the very top... being a dumbass I figured the gauge must've finally went, my car wasn't showing any signs of overheating.
I hopped onto the pkwy and drove toward my exit got about a mile from my exit when I started to notice pinging (marbles in the intake sound) and I started smoking, I pulled over immediately, and upon pulling to a stop the car stalled. I ended up calling a tow truck, but when he showed up he already had someone on the bed and he told me he had to drop them off then he'd be back. I popped the hood and noticed coolant had puked over the front bumper, and a little bit of the top of the hood. Every time I tried to start it there was a knock and pinging, after letting it cool for a little it started up and sounded normal, however I had to open the throttle a few times to get it to run without cutting out but once I did that it idled... roughly but it still idled. I limped it hope pulling over every time the gauge shot up (which seemed to be less than a minute).
I haven't checked anything today but here's some things I know which are wrong...
I need a new pressure cap, I noticed a coolant drip from the cap the other day, not gushing, just a very very slow drip but it still means it's not holding the pressure like it should right?
The thermostat is a month old at most... I checked it before putting it on and made sure to drill a hole in it.
The clutch fan is broken and I have an electric one I wanted to put in today, but it still gets hot on the pkwy so that wouldn't be my only problem right?
The plastic air dam is missing, I don't think it had one to begin with and I changed my lx to a gt so I'd have to see where it goes and what it looks like then I'll make my own.
I noticed my coolant looks green but when I pulled the sensor out of the overflow it looked almost like the milkshake color you get when you get oil and coolant mixed.
I figured my problem is a combination of these things, I just wanted to know where to start as far as checking to see if I screwed anything up (pressure test etc...), if there's a way to check to see if my radiator has blockages and if the water pump is shot, and if you guys think the lower octane fuel could also be a cause of the car getting so hot so quickly, since it's never shot up like that it only gets really hot on the pkwy usually it's right at the "M" in the normal during driving around town(yes it's a stock gauge, yes I plan on changing it when I get the money). I appreciate all the help guys.
