jimmy loss power

when i turn it on runs good for like three to four block then it losses power i floor it dont run like should i did a full tune up and computer still tell me miss fire and 3-2 control solenoid dont get it i need help

Please let us know what year and motor you have. Are there any codes?

1995 jimmy v6 4x4 vortex motor dont know to much just bought it last month i thought it was the spider injecter then chaged the fuel filter, spark plugs, wires, cap, rotorand oil change, new tires same size, air filter, cleaned intake , and change the cat. and change trans oil filter since the service light is on i took it get it came out that 3-2 solenoid and miss fire they told me to do a tune up so i did again so i did it still come out the same thing i dont have no ideas what else but to change the solenoid thats all i havent changed

1995 jimmy with votrex motor v6 4x4 dont now to much i just got it a month i changed spark plugs,wires,cap,rotor,spider injecter,fuel filter,air filter,trans filter,oil change,trans oil change,and cat,new tire the same size and then i toook it to garage because sevice light on so it told me it the 3-2 solenoid and it miss fire they told to do a tune up i did again it still the same and i took it back it tells me same thing all i havent chaged is the solenoid

Was the solenoid code there before you changed the filter?\
What is the code no?
And any other code no?

If you are getting a missfire code you have a engine miss.
I would make sure the fuel pressure is up to par to start with.
What kind of spark plugs are you using?
Can you feel the engine miss?

dont know if this it dct p1886 thats whats on the paper they give me you cant feel the miss

P1886 is 3-2 shift solenoid electrical circuit.
Check all wiring and plugins and for 12 volt power to solenoid.
Did it have code before filter change?
The transmission problem should not cause engine power lose.

Go over your basic tune up.
What kind of spark plugs did you put in it?
What is the fuel pressure when it loses power?

i think they was deco something like that my dad says that it its not a loss power he says that when it warm up it dives on high gears he thinks it the solenoid what you think

The code you gave is for a 3-2 shift solenoid.

Recheck for codes and see if there is any other codes.

Is the transmission still shifting up good in all gears or is it locked in one gear.
If trans is locked in 2 or 3 gear the engine should still have power in that gear range.
But may lack take off power from a stop.

Proper testing should lead you to the problem.

it takes off and shifts good when you first turn it on then like two minutes it like stays high gears when it starts i notice dont pass 2rpms it does when i turn it on

Time for a Good engine/transmission capable scanner.
post back codes.

Just wondering if you found your problem?? I'm having the same problem only I took it to autozone and they didn't tell me the code # but they said it read that there was a misfire on the #3 cylinder and I did a full tune up and mine isn't running any better either!!:banghead:

If you want to start a new Thread/post and give model and year and engine and other info some one will help you.
Ac /DeLco plugs?

yesterday it drove perfect and now my trunk dont open it did open when it was on park does it have do was the shifter or sencer

Proper testing will tell the story.
