1994 Ford f150 no power!

I've got a 94' F150 302 with an E40D aod tranny, and 355 gears. It's so underpowered that a small hill or strong wind drops it out of overdrive. It's driving me nuts. I've got to do something to get more power out of it. Is a power chip the right way to go or should I also change throttle body, camshaft, ect. Any info. would be much appreciated.

I have read alot into these chips and as it turns out what they do is overtune the engine. Go to www.bankspower.com and start reading about chips also while you are there see if they have any packages for your specific vehicles for engine and transmission chips. I have put on headers a full exhaust complete ignition system and a few other goodies and they have all helped but I still am going to get some banks equipment for the hog. If you want to see a drastic difference change to 3.73 or 4.1 gears that would be a gauranteed improvement on the truck. Also if you have a large sum of miles maybe it just needs freshening up a bit. Also for the most bang for your buck a supercharger but that is getting on the steep end of the bottom line. Hope this helps some.

I thought about changing gears. Unfortunately that gets really expensive as well. I've got 91,000 miles on it, I'm not sure how many miles to expect out of the 302. It doesn't use any oil, if it did I'd probably put in a 351. I've heard good things about changing the throttle body and getting a chip. But I don't know if the improvement would be as drastic as a gear change.

[font size="1" color="#FF0000"]LAST EDITED ON 22-Oct-01 AT 05:12 PM (EST)[/font][p]I recommend installing a performance cat-back exhuast. My 302's both woke up after a exhuast system was installed. A FIPK is the next best thing, and then a ignition system. I'm against chips. I had one in my 93 F-150, and it did help some, but not enough to justify using 91 octane gas.

302's can easily last 200k+ if maintained properly.


BTW, If you don't use cruise, the tranny will not downshift.

FIPK is Fuel Injection Performance Kit. K&N makes a good one

I have the exact same problem. I installed headers and a K&N air filter but that made no difference(except for minor fuel efficiency gains). You have to remeber it's a 3 ton truck. If you replace the 3.55 with 3.73 you know there will be a diference in power. With computer chips and some exhaust mods it's always a gamble. In my opinion anyway. I'd spend the extra cash and get gears. Specially if it's a 2x4. If it's a 4x4 you'll have to do both diffs and that's obviously more money. Good luck

It's a 4x4. From what I have read the e40d trans has a ratio of .67 in overdrive. If you run the numbers with my gears and tire size that means the engine is only running about 1500 rpm at 60mph. I don't think a 302 can pull a 3 ton truck up a hill at 1500 rpm. It's not in the power range. For this reason I would guess a gear change will do far more good than any engine mods. But for what it will cost to do both axles I could probably buy a supercharger!

True enough. I read that if the fuel injection system is a MAF controlled system you can do all kinds of mods to the engine and the ECM will handle them;ie: cam, supercharger, heads etc.. but if it's a speed density controlled, you first have to switch it to mass air flow or the computer will not understand the changes and the engine will run poorly. The 5.0 is a tough engine and there are alot of aftermarket add ons for it out there.

I restore late 60's mustangs on the side and know all kinds of tricks for carbureted engines. But I'm new to efi engine mods. My pickup has MAF and I was thinking a compucam camshaft, computer chip, k&n filter, and cat back exhaust would be a good combination to try. Any comments?

That's the nature of a 302. It has absolutely horrible low-end torque. It needs to be rapped up to get good torque. That's where lower gears come in.

I highly advise gears. I would go with 4:10's. I've been quoted $650 for a gear swap on my '89. And Yes that's both axles.

mattv1, what size tires are you running on your truck? I put on 31" tires on my 95 Bronco and there was a drastic decrease in power. I had to recalibrate the speedometer (PSOM) which made a huge difference. Let me know if you need info on how to check your speedo settings or want to change it, it's very easy. Good luck, Ben

[font size="1" color="#FF0000"]LAST EDITED ON 25-Oct-01 AT 09:24 AM (EST)[/font][p]It's got 32" tires on it and yes I know that alone is killing a lot of power. It's actually fairly peppy around town but on the highway it's a turd. I read some posts from another user who is losing power at highway speeds and getting bad mileage. People think he has plugged up cat's. The best I ever get is 12mpg average is probably 9-10mpg. Is this normal, or are you guys getting better than that. By the way my exhaust system is the original from the factory. 94" 302 AOD 91,000 miles. To answer the speedometer question - The tranny went out at 79,000 miles (OUCH)and the tranny shop recalibrated it.

[font size="1" color="#FF0000"]LAST EDITED ON 25-Oct-01 AT 10:10 AM (EST)[/font][p]Pastmaster, I've checked around most people are quoting me around $750 per axle! Where did you find someone to do them both for $650. Another kind of stupid question. Does the 94' use a Dana 44 front axle?

[font size="1" color="#FF0000"]LAST EDITED ON 25-Oct-01 AT 02:59 PM (EST)[/font][p]Dude,

This isn't even funny. I was just about to ask you in your other post if you've experienced any loss of power in your truck. After reading this, I have to ask you something. When was the last time you had your tranny fluid changed? Are you noticing any "shudder" when driving? If the tranny fluid's old, it could be the very reason for your problems. When the tranny fluid ages it's properties break down. If they break down enough, they can keep your torque converter from engaging fully through loss of pressure, thus loss of power (not shifting properly). This may be something you want to consider.

Hope this helps.
Cragar

Oops! Just noticed that you said the tranny went out at 79,000 miles. Therefore, I doubt that to be the problem. I'll keep thinking, though. Later!
