Car: 1998 Pontiac Grandprix
Engine: 3800 V6 L36 N/A
Problem: I was driving normally as I pulled up to a stoplight, engine already at normal running temperature.
As I came to a stop I noticed the car was idling rougher than normal. I drove another half mile through town and the service engine light came on as I pulled into a fuel station, engine running extremely rough.
As I came to a stop next to the fuel pump the car was shaking so much it felt like I was riding a wooden roller coaster flying down a gravel road littered with potholes.
I turned the car off, popped the hood up and everything seemed normal except for a strong smell of antifreeze burning. Engine wasn't hot and there was no smoke to be seen.
I decided on trying to start the car to see if the problem persisted.
The engine turned over about half way and stopped just as if the battery was dead, but I knew the battery wasn't dead.
I waited for about 20 minutes and tried to start it again, and this time the engine started but was running extremely rough as it was before, so I turned it off again and just called AAA and had it towed home.
By the time it got home it had been several hours so I tried turning it on again seeing as the engine was cooled off.
The car started as it normally does and idled smooth as ever. After a minute or 2 white smoke was barreling out of the exhaust, but the car was still idling smooth. Gave it a few more minutes and the rough idling began.
Its been a while since this happened and it still starts and runs normally until it gets warm so im thinking its a blown head gasket, but im not sure.
what do yall think?
