1993 Toyota 4Runner Question: car runs rough
Its hard to determine if the smell could be a leaking valve cover gasket that is allowing a small amount of engine oil to drip from the top of the engine down onto the exhaust manifolds. Your Toyota has a distributor cap, spark plug wires and spark plugs and of which could cause the engine to run rough if they have failed. Trouble codes are easily retrieved from this Toyota as it has OBD1 diagnostic capabilities. Your Toyota has valves that have the valve clearances adjusted with "shims". If the valve covers are removed or a cylinder mis fire is related to low compression it is important to check and adjust the valve clearances. If the valve cover is off to repair an oil leak definitely have the clearances checked! - patrick mannion

My car runs rough. I have a P0301(Cylinder 1 misfire) error code. I have changed the sparkplugs, switched the coil, and have used about a half a tank of gas that has Lucas fuel injector cleaner in it and still have a P0301 error. Fuel injector?
My question says it all... The check engine light blinks, sometimes stays on continuously, and sometimes does not display at all, seems that the problem is intermediate. Thoughts?
