Now power

[Buschboxer]

I am having some problems. It feels like cats are plugged but they aren't, any other ideas for this type of loss of power?

What's the year of the Bronco? How many miles are on it?

 

[Buschboxer]

It is an 87 with 140,000 miles.

140K is a bit of milage... Can you get into what's going on and what your engine/tranny set up is and if you have a lift or tires or any "modifications" to anything? Make a signature, it's the easiest to do and it'll give everyone an idea of what you're running with.

Did it suddenly lose power that it's had or is it just starting to feel like it doesn't pull like it used to ?

yo,

Do a SELF TEST - ; COMPREHENSIVE; Includes Steps to Clear Continuous Memory & Keep Alive Memory (KAM)Codes; & a list of reasons why a technician may see the MIL lamp lit with no accompanying Continuous Memory Self-Test codes Source: by Steve83

As you can see, some tests (Dynamic Response Check, etc...Steve did del some of these from his narrative) within KOER mode require Ford's STAR Tester...

IF you get a DTC, post it here.

If no DTCs;

Check Timing,.. i forget what you have done so far; I do recall a post where you wrote about a recent tune-up and TV cable. When you adj the TV pressure, did you use the pressure gauge method? and how did that rubber bushing @ the TB look?

Am wondering if the Self test brings up a TPS code....

and if it does, it could be putting it into a Limp Mode (2nd gear)

GL!

Last month you posted that you thought that you had a bad transmission.

Did you get that ruled out?

This post really gives us nothing to work with.

When was the last time it had a tune up?

Does it stall or throw any codes?

As BroncoBill78 asked was the loss sudden, or gradual?

Does it idle well?

Is it hard to start?

Did you do a compression test? Your timing chain could have jumped a tooth.

We'll try to help, but you gotta give us something to work with.

Sorry about the lack of info, I didn't know if my tranny was shot, it doesn't seem to have any trouble shifting anymore, but then again It hasn't been driven much. Tomorrow I am going to dig into it more, pull codes, check the timing. I will also do a compression test. I did a tune up in October of last year, it doesn't have 500 miles on the tune up, It has issues idling right away when it is started, then after it warms up it idles fine. It does stall if it I try to drive it before it is warmed up. The loss of power was gradual. It hasn't gotten any worse, but it has diffeculty accelerating and holding speeds. I will post more tomorrow. It feels like the fuel air mixture is off, so hopefully it throws some codes.

Right off the top of my a$$ it sounds more like an induction issue. Best advise I can hand out is to follow Miesk's advise and let us know what the results are. With more info everyone here can probably help you narrow it down. Chances are you're looking at a cascade failure and that's causing the problem but hey, what do I know <grin>. Follow up on what Miesk had to say & let us know.

I checked the codes yesterday, and the TPS was the only code it though, So I replaced it, that fixed the idle issue, and to some extent the power loss, but I haven't gained it all back. When I adjusted the tv cable, I got the method from a mechanic at the ford delership. I can't remember exactly what the measurement was but I moved it all the way one way, then measured put a mark, then moved it all the way the opposite direction marked the same measure ment then place the lock in the middle of the two marks. I looked up the specs on when it is supposed to shift, it was right on. It shifts really well right now. If that is not right, please let me know, I will do it differently. The rubber bushing @ the TB looked good. Also checked the timing, no problems there.

Thanks for the link, will definately do that.
