Engine Performance problem
1992 Honda Prelude 4 cyl Front Wheel Drive Automatic 188000 miles
My 1992 Prelude has idle issues after being started.
once I crank it, it will instantly idle at 2000 rpms for about 5 seconds. Then drop and jump between 1000 and 1700 rpms.
at it's low of 1000 rpms it will choke and cough-up light white smoke from the tail pipe.
there is also an audible light 'pop' noise from the lower drivers side of the engine block.
it only does this in park and neutral.
when placed in gear it will sit strongly at 1300 rpms.
this problem started one evening after I tightened the oil pan bolts to stop an oil leak. While the front of the vehicle was lifted aprox. 8 inches from normal height, I started the engine and reved it to 6000 rpms for 2 seconds. Upon the rpms returning to idle, this problem started.
if it's any help, I later noticed that the vehicle's air filter is slightly punctured in a few of the grooves.
i also cleaned the iacv filter. No help.
any help is well appreciated.
have the same problem?
