ok guys..still having n/a troubles..my car started my wanting to die evrynow and then when you were to rev it and let off the pedal. it would idle down and stall out. next came a deep black smoke at idle and then to not idling at all. i replaced the timing belt and tensioner/idler. after all this the car doesnt smoke. but seems to miss a little and not idle at all.from reading other posts, ive came down to the MAF being bad. is there any way to tell if its bad or not? Also when im under the hood, keeping the car running by reving it at the throttle body, ive tried unplugging the maf and it doesnt seem to affect it at all..ive cleaned it, the inside of the throttle body etc..no help ...any suggestions guys?
