Does a 1988 Chevy 1500 have a transmission vacuum modulator?

More Info, If You Do Not Find A Modulator, You Could Have a
Different Trans. If You Have A Square Pan With 16 Bolts Then You
Have A 4L60 or TH700( no modulator on these) If the pan is oval and
17 Bolts Has 4L80 ( no modulator on these) Hope This Helps You
Should Have A TH400 Trans & It Does Have A Modulator.

How do you change a fuel injector on 95 Sunfire?

I've had two injectors replaced on my '96. It's a lot more
direct
than I thought it would be.
Naturally, I suggest picking up a Haynes or Chilton manual
for your car. Their photos and text make the job easy to
understand.
I'm not really sure I can describe the job here with enough
detail
to let you run out to the garage and have at it, though.
Basically, you have to remove the cover from the throttle cable.
It's the black
boxy lookin' thing on the passenger side of the engine behind
the valve cover,
into which the throttle cable enters.
Then, remove the throttle cable so you can get at the bolts to
remove the entire
throttle assembly.
Next, locate and remove the long, narrow plate that retains the
injectors. Mine
has a couple of Torx screws holding it on. That plate runs
across the engine and
covers just enough of each injector to keep it from popping out.
It should be
fairly obvious.
You have to remove the electrical connector from the injector,
but frankly, I don't
remember if you want to do that before or after you pull the
injector out of it's
seat.
I bought my new injectors at Auto Zone for about $76 each, but
just watched
as my mechanic installed them. I replaced them one at a time,
twice. (chasing a leak)
My mechanic did it for a 12 pack of beer each time. She's
awesome! Anywhere else
would have been quite expensive.
Anyway, when she put the new injectors in, she put, I guess,
some Vaseline on the
outside of the injector bodies. I guess this lets them slide in
easily and
keeps the O rings supple. And DO replace the O rings! New ones
should come
in the injector container. (Ask around. The Vaseline stuff she
used, might have
been some special, auto oriented lube.)
Then she just slipped them back into the seats. We had to push
them down pretty
hard to get them seated properly.
Following all of that, put everything back together, fire the
old girl up, and
see that she runs OK and that there are no leaks. If you DO have
a small leak,
try rotating the injector in it's seat a little bit. Sometimes
the O rings just need a little help
to seat right. Also, trusted mechanic says that sometimes a
small leak will go away
in a day or two as the O ring finds it's home.
If you have a BIG leak, you've done something wrong and have to
go back
to square one, or, you got a bad injector (unlikely) and you
still have to go
back to square one.
Hope this helps. Get the Haynes Manual!
Let us know how everything turns out, OK?
