was running 90 shot of dry shot nitrous when the engine seized up for a second wheels locked and I slid on the road for a second, then the wheels started spinning and I regained control, then I noticed that my idle sounded like crap. I parked it and let it run for a minute, no fluids leaks from the car but I could see and smell gas coming from the exhaust. no ding or pinging coming from the car while it idles just sounds like 1 or 2 pistons aren't firing. engine shakes a lot now though.
I went and pulled all the spark plugs, all looked good none melted, 1 did have a small amount of oil on it. I bought all new spark plugs and still the same problem persists, bad idle loss of power and gas smell from exhaust.
all wiring looks good.
what would be most likely problem, nos broke the valves? head gasket? I don't think its a broke piston rod because no ding sounds.
warped head? or piston ring? id like to know most likely problem and possible cost to fix in a shop, I don't have the tools to do it myself
