(Excuse my english) My dad gave me a '98 honda crv. since it came from being serviced after an oil pump failure, it has no power when it's cold I have to press the gas until the engine warms up. I have taken it to various mechanics but they can't find the problem, they only increased the idle power (It uses a lot more gas). I have replaced all the sparkplugs twice to no avail. The only thing I have noticed is that, whenever you remove the sparkplugs' ignition wire and the engine is ON, it will react (losing power) to only three, but not to the last one. it's as if that sparkplug is not contributing any power to the engine.
Any solution that doesn't involve changing the whole engine?
