Currently my 94 4.6 bird is parked and my project car. Not a daily driver anymore but it is in running condition. It has 147,000 miles, and ive owned it for over 3 years.
When its cold at initial startup it idles nicely, however you must wait a few minutes for it to warm up before you can accelerate the engine. Dosent matter if youre in park or trying to drive down the road, it dosent like to accelerate at all. if you push the pedal any more than idle speed, it just bogs down. So slow that other drivers on the road get mad. Once it warms up the engine runs decently, however if you press the pedal to WOT it will bog down terribly. Its almost like mashing the brakes rather than mashing the gas. its been like this as long as ive owned it. Overall the car runs well. gets decent milage, about 17-20mpg.
Im certain its not the tranny, cause even if its running parked and you hit WOT it acts exactly the same. As well i changed the tranny fluid as recommended here to get rid of the "shudder" issue.
Heres a few tidbits for background. The CEL has been on since i've owned it. the only code it throws is O2 Sensors. Honestly, since the car continues to pass smog wonderfully i have been cheap and not replaced them.
Tomorrow just for fun I'm going to clean the MAF, though i havent ever inspected it to see if its dirty.(note, im still running the stock airbox with the silencer removed).
The engine does emit some blue smoke on startup, and does comsume oil as i have to add at least a quart of oil between changes.
in your collective experiences, has anyone experienced anything similar from bad O2 sensors? Dirty MAF? Something else entirely?
Thanks everyone!
