Service Engine Light?

Post by Andy Jones »

I'm having some problems with my Bronco right now. When I'm Driving down the Highway at about 65-70mph. my taconmoter(sp) will jump in between 1800 and 2000 rpm. then the service Engine light will come on. then if i put my foot into it a little more, the light will go off! Does anyone know what could be happening? is my tranny going out :cry: it a 95 xlt with a 5.8 MAF and E4od trans. I'm not working right now so money is really tight!! need some help quick!

P.S do these things have a saved faults in the computer? so if i go somewhere to check code's they will come up with the check engine light off? and where can i go to get the codes pulled?

There should be information saved in the ECM. It doesn't stay forever, though, so I would check it soon after the light has been on.

Is the transmission changing gears when this happens?

I think that you may need to get a reader. Reading through the check engine light can be a PITA. Looks as though your truck is a 3 digit code truck. When you get your codes you will get hard faults first a separator code of 111 111 then your intermittent codes. The process will keep repeating till you pull the wire. It sounds like you should have at least an intermitent code. Here is a link to what the codes mean. http://www.troublecodes.net/Ford/
Hopes this helps.
As far as digits I think around 94 is when three digit codes came into effect. If your truck is a california truck then it may be OBDII. Not a big difference but the processors have 104 pins and a few different codes.
As far as getting the codes pulled some of the parts stores like Kragen will loan you a code reader if they still allow it. (they stopped doing it in my area). The computer usually will record the intermittent code (when the light comes on and then goes off) for a few key cycles.
A couple of items that may go out that are ignition related but may not really set a code are the stator, coil, or TFI module. Try and get the codes read then go from there first.

Usually if there is a transmission problem you will see the OD light flash.

If you have a MAF it should be a ODBII truck.

You are in luck. Your truck has the OBD that can be read with the checker. Buy one and it will come with the decoder manual. Borrow one from Autozone and use theri manual. Owning your own checker is just part of the cost of ownership. Get one. Read the codes and tell us what you get and we can go from there.

I'm going to take a stab in the dark and say that you have an EEC5 or ODB1 truck. ODB2 was only in 96s. It is definately 3 digit codes.

Fordfuelinjection.com has a full list of the KOEO codes, and how to check them.
