1987 ford ranger 2.3ltr
hey guys i need some help...
i dont know what this is..
my parents took my truck to some cheap automotive shop while i was in basic..
and before it ran great now it bogs alot, sometimes before it shifts it starts to kick and bog back, i have to release the gas pedal for it to shift but even then i cant go faster than like 45 or it starts kicking and bogging erratically, and also when i got the truck back i found this laying around

the part number on it reads E57E-CA BMC1
and as for the image just right click and open in new tab

i also cleaned my IAC, and i found a vacuum hose that was disconnected i reconnected it and now it runs a little bit better but i still have the bogging and kicking issue...
any help will be greatly appreciated
thanks so much for welcoming me to FTE
nice to be surrounded by ford lovers

 

Is it fuel injected or does it have a carb. It sounds like a fuel system/ pressure issue. Also, how long did it sit? It doesn't take a real long time for carbs to get clogged up with the cheap fuel that is around these days.

 

it is fuel injected and i was suspecting some kind of fuel pressure issue just not exactly sure what the prob is. i have been searching online for some kind of parts fiche but i cant find anything..
thanks for the reply

 

Try filling the tank with a high quality gas and add Sea foam while doing so. This should clean out the fuel system, including the injectors.

 

Look on the bottom side the hood and on the radiator support for a vacuum line diagram. If you find it, follow each of the hoses and insure that it is connected per the diagram.
You have a distributor for ignition, right? It sounds like the timing is way retarded. Disconnect the 'spout' jumper and set the timing to 10BTDC at hot idle. The engine has to be warmed up, but I don't remember why...
Once you have the base timing set, re-install the jumper wire to enable the ECM to control ignition timing. You may find you have gained back a lot of your lost power.
You can buy or borrow a fuel pressure gauge that screws onto the injector schrader near the rear of the engine. Pressure should build after you turn the key from Off to On, [not Run], and should maintain pressure for at least a little while. I think the pressure should be in the 40 psi range. You can also use the gauge to 'flow' test the pump and filter by running the engine, and draining off a measured amount of fuel through the release valve on the gauge. If it delivers XX Oz of fuel in 15 seconds, it will deliver XX times 240 Oz if fuel in an hour. You should see huge numbers if you do the math and the pump is working.

thanks and today i also noticed that this sensor off of my intake is broken, if possible can somebody tell me what it is and what it does???

fixed the images
now just click the links

 

Much better, I think that the air temp sensor? Just a guess, it's on the intake manifold right?

 

Fuel Filter?

 

It looks like the intake air temperature (IAT) sensor to me. It can be removed and checked to see if it is fouled or dirty. If so, you need to find the source of the dirt in the ait intake system, correct it and clean up everything from the dirt source through the carb and engine.

 

The closest thing I can find in the '85 EVTM is the Air Charge Temperature Sensor, but it is mounted in the lower half of the intake, on the rear side. If you remove it, the sensor should look like a little 'bean' with two wires connected to it. You can remove it, clean it, and re-install using teflon tape if you think it is dirty.

thanks going to get a replacement today and see if it helps at all, ive read that if it is bad it can cause rough idling when cold and stumbling on acceleration when it is cold and these sound like the symptoms i have been having...
ill be back later with an update
thanks alot for everything guys..

 

hey guys i just found out that it wasn't a air temp sensor but it was in fact a knock sensor, dont really know how not having one will affect my engine and what exactly it does..
any insight????
