Well i looked around the site, and i couldnt really find what i was looking for, especially anything recent.
I have a 1987 5.0, the car seems sluggish and sometimes bucks a ltitle bit if im doing 60 in 4th and give it soem gas, it used to pick up much better.
Within the last 2 weeks i have: Changed plugs , cap, wires, rotor, fuel filter and dumped some injector cleaner in, and also an oil change.
It made a bit of a difference but theres still something not right. I checked the fuel pressure and while runnign it was sitting at approx 35 psi and when i cracked the throttle it bounced to around 45 psi. I have bumped the timing ahead alittle. hmmm what else That would be about it.
Now my questions: How volume of fuel should my fuel pump put out.. like how many mililiters should it put out in a minute. So if the fuel pump does put out the right volume would my injectors possibly be lazy???
And secondly... Could it possibly be my 02 sensors? Whoever built the exhaust before i got the car put two seperate o2's in above the cats and didnt connect them (has small crosspipe aboout 1 inch halfway down the car) Will that make it harder to diagnos bad o2's when i plug it into the computer at work???
If anyones got some answers or advice lemme know!
