New 94 gt!

I just bought a 94 gt auto with 4.10s and a cai. Something just seems to not be right tho. I can't even spin the wheels .. It has like no torque . Shifts hard sometimes. Knowing it has 4.10s . I would think i could at least scratch in 1st. Any help please? Thank yiu

Re: New 94 gt!

Welcome!
Does the engine rev up high when you try to take off, like the trans is slipping, or is it just dogging out on you?

Re: New 94 gt!

I would guess its something fuel related. Try changing the fuel filter and see what that may bring. Could be the pressure regulator as well.

I hope it's as easy as that. As long as it's not the trans

You should be able to light them tires on fire taking off. Hell my 3.8 will spin the tires taking off a little and it has 2.73 gears. Something is definitely wrong.

Re: New 94 gt!

After we swapped a 5.0 out of an '89 stang into my old Bronco II that had been sitting for years in a field, it ran ok for a little bit, then it did the same thing as what you are describing. Changed the fuel filter, and it was all good again. Next day I fire it up and it was doing the same thing, no go. Ended up having to drop the fuel tank and **** you not, there was about 3/4 of an inch of dirt in the bottom of it. Cleaned that out, changed the filter again, and it ran like a top.

Re: New 94 gt!

Ha, yeah, I can smoke the crap out of my 04 v6... Yeah it has 3.27s and a 5speed, but still, about the same tq.

Edit: ha, well, atleast the back right tire.

I bought my 94 about six years ago and I had the same problem , I'd floor it and it had a real slow reaction so I took it to my uncles performance shop and it turned out that my Mass Air Sensor was dirty so he cleaned it up put back on, when I got the car back it was night and day difference before I put my gears in!! So check that out as well !

I believe he used Carburetor Cleaner, just spray it on the wires inside and let it air dry don't wipe it , cause if you damage them or break them, then you'll have to buy a new MAFS which can get upwards of $250-$325 or a used one from eBay or somewhere like that for like $50

No residue electronics cleaner. You can pick it up at any parts store.

Have you done a full tune up on the car ? Make sure timing is were it needs to be ? I would also get a fuel regulation Gage and hook it up to fuel rail and make sure you are getting the correct pressure.

Should I go ahead and advance the timing about 10 degrees if it's where it's supposed to be?

You can and see if that changes anything. When you take off the car is underpowered right? Does the Motor run bad or miss? I would check and make sure all cylinders are firing and that you have correct fuel pressure. Have you owned the car long?

Have the car running and take a pair of pliers with rubber on the end of it to keep from getting shocked. Remove one spark plug wire from the cap at a time . If it makes a difference in the way the motor runs then the plug is good . Replace it back and go to the next . And if one of them does not make a difference then the plug is bad or possible the wire.

Pull out plugs to see if they are wet with oil or fuel. They should not have any oil or fuel that you can feel. They might smell like fuel but as long as they are not wet . Let me know if any are and what cylinder also same thing on the thing I posted before

If you can get a hold of a fuel pressure Gage that would help to rule out the fuel pressure issue.
