Rough idle on 99 chevy metro 1.3l engine. changed plugs good pickup but intermittent misfires. even when idling. also leak in exhaust system.


First thing, fix leaking exhaust, this can cause erratic idling...second thing, remove and clean IAC valve and MAF sensor..dry and replace, also try putting some SeaFoam in the petrol, engine oil and air intake, let sit for 10 minutes then go for 10-15 min drive...suggest you change engine oil shortly after driving about 5000kms, if the oil is old..

Did you get any codes on the misfire? If you did not, test ignition coils, test vacuum, test fuel injectors, verify correct plugs..That's right, anything from a fouled spark-plugs to burned cylinder head valves can cause a misfire. Whatever the root cause of the misfire, the bottom line is that one or more cylinders are not contributing to total engine power output. This leads to power loss, rough idle, unstable RPM and bad gas mileage...cheers

2002 4.8l gmc yukon oil pressure problem


My suggestion would be to check it with a mechanical gauge.
You would need to use a Tee fitting to use the sensor to have fuel pressure.
If the mechanical gauge shows steady pressure at idle, it could be a problem in the wiring or the instrument cluster.

Oil pressure drops and rises,, I have checked the sending unit, does theoil pump have fiber gears?


No, the oil pump has steel rotors. The oil pressure is supposed to rise and fall a certain amount, it's normal. As long as the warning light is not coming on at idle, you should be fine.
