bell1255:Without AC your RPM at 1100 is too high. It should be btw 600 and 800 depending on the vehicle sha. Kindly check your idle system if it has one. Clean your throttle body if its dirty. Do you have a misfire code? Scan the ECU if you have the CEL on... Also check the compressor and the belt. Is it the right compressor thats fitted to the engine? |

bell1255:Nope they are not. Buy genuine iridium spark plugs, you can buy from radautoworks or import from amazon. It's about 3k for only one. That's about 12k in total. Also get genuine coils. But your engine will breathe a new life. Also scan to check for error codes. 2 Likes |
