Hello, I have a 94 f-250 with the 5.8 and I noticed the other day that I had a lot of fan noise and loss of power so I replaced the fan clutch which was bad. I'm still having the same problem though. I know it needs some new plugs and probaly new wires and rotor but I don;t understand the whole fan thing. The oil pressure has always been low on the truck but it has always ran great and had no knocks or ticks. Any advice? |

| Can anyone tell me why Ford designed the exhaust manifold for the 4.9L the way they did? I can see no reason for it other than possibly the installation of a turbo or something. I would truly like to know so if you can answer the question, I will be watching out for it and will appreciate it. Thankyou, Mike9408 | |
I have a 1987 Ford F150 (4.9 300ci FI 4x4. 4 speed manual) I have a problem when it warms up it starts choking and stalling.. I replaced the fuel filter because I thought it had some trash in the tank but It still stalls when it gets warm. I am sure I have enough gas but I am lost. Could it be the Rotor cap and button?. I don't think it is the catalytic convert. for it doesn't glow when hot. Cn any one help me?

| Could this be a bad knock sensor. Both converters have been replaced within the last year with the o/2 sensors. Scanner reads o2 sensor and new converters are working ok. Also MAF reads good. 158 compression in cyl. and vacuum pressure is good. Yet I have no power unless I rev up the motor to about 3000rpm and then let off the clutch. this is the same in all gears, even at 45 mph ( until engine speed is upword around 3000rpm). Can I just unplug the knock sensor to test or is there another way? Thx for the help!! | |
