85 turbo - coughs on heavy accel load

Dang, that's odd... I knew that part number sounded familiar, and sure
enough that is as best I can figure the modern equivalent of the stock
spark plug for a '56 Packard or Stude Golden Hawk. Never seen it used
anywhere else.

Nothing really to contribute other than to comment on that, and make a
mental note to ask for plugs for a '85 2.2 turbo next time I need a set
for a Packard motor. Saves a lot of explaining, it does.

Note in particular that the hoses in the convolute tube that run along
the back of the valve cover, and the fuel injector wiring harness,
have a tendency to get cooked.

 

Sounds to me like simple ignition weakness. Plugs and/or wires
shot, distributor cap worn out (did that model still have a
distributor?), coil weak. The spark has the hardest time jumping the
gap under the highest compression pressures, and that happens at
low-to-mid RPMs and wide-open throttle. Any weakening of the spark will
result in hesitation.

IIRC, RNxxYC is the stock plug for smallblock Mopars, where xx indicates
heat range (12 & 14 being typical). So there are a few million
applications for you Big block Mopars use the RJxxYC (shorter thread
reach) series plug.

 

Thanks! That's more helpful than you know; a J12Y is the stock plug
for a Studebaker R-series (Avanti high compression) motor. Guess what
else I have laying around Makes life easier when you aren't near a
"good" parts store and the counter guy claims he needs an application,
he can't just look up a J12Y (and why not?) but of course his
computerized thingy only goes back to 1969 or whatever.

Now that I think about it, I don't think I've ever replaced the plugs
in any MoPars, just cleaned them and kept on rolling. My MoPar-owning
phase coincided nicely with my "broke as heck" phase

As usual, this source has given half-correct information. Yes, Bosch plugs
fail early and often. Their regular plugs used to be OK until production
was moved to China about 18 months ago. Their platinum plugs have never
been a wise choice in a Chrysler turbo engine.

But no, you don't have to "USE ONLY CHAMPION". Any well-made plug of the
correct configuration and heat range will do just fine, and my experience
has been that Champions' quality control is too inconsistent to rely on. I
used to favor Autolites, and still use them from time to time, but I've
come to like NGKs quite a bit -- they're of consistently high quality.

More horseshit from damnnickname. There is no way a spark plug can alter
the "timing of the power module".

 

Daniel you are putting your foot back in your mouth again, Idle was
controlled by the timing back then, With autolite/bosh and some other
plugs.I say use Champion because I no that was the only one that I know
didnt create a problem. The Power Module saw the resistors in them and
caused the timing to jump all over, causing extreme idle problems
hesitation problems and more, , I have fixed many a problem at the dealer by
simply removing the those plugs and installing Champions, If you dont know
what you are talking about maybe you should put your key board up... I would
bet you are one of those guys that put everypart on the car untill given up
and told your cust to take it to the dealer... Is that so? The next time you
get one of these vehicles, put a timing lite on it and see for youself, but
then again I bet you dont know how to use one

It had nothing to do with failing

And here once again, you have no clue what you are talking about
Stick with the voltmeter and regulator, you are good at bullshitting your
customers with that

 

Just for information - the wastegate control solenoid that allows
vacuum to go to the wastegate - exactly when does the computer turn
that on, or off? Why does it need to control when vacuum can get to it
or not, I mean, what would happen if the vacuum was just routed to the
wastegate all the time instead of on and off? thanks

 

If you were to route vacuum to the waste gate all the time you would loose
the boost. here is a good site that may answer any questions you have

Dunno, good question. 4318039AB (and its predecessor 4318039) smells quite

Now there is something I would have to agree with DS
