Question about 1985 Jeep CJ7

1 Answer

Cj7 w/15cid 4-cyl running bad after tuneup?

Hey, im not mechanic so help me out if you can. i have a 1985 cj7 with the 4 banger. just got it, and it ran well enough, but i wanted to tune it up. replaced the distributor cap, button/rotor and plug wires. i may have screwed up and put the wires out of order on the cap and started it up. of course it would not run. replaced the wires in the correct manner (per haynes), and it ran really really rough at low RPMs. i switched everything back to the original wires, cap and button, and it still runs poorly at lower RPMs. i have since replaced the plugs with an upper grade plug, and it still is rough. I pulled the plugs, and #2 was pretty mucked up--after about 100 miles. cleaned it, and she still runs pretty poorly. poor response, rough idle, just plain old rough. at 2000 or higher (estimated) RPMs, it seems just fine.

did i screw up a cylinder by mixing up the spark order, or ???. i thought maybe i had the wrong cap/button, but even after going back to the old ones it still was rough. what do you think? any help is greatly appreciated.

How do I trouble shoot no cold start?


hi bob,
what engine ? 2.5L V6 or 2.0 L 4 banger?
does it crank, if it don't crank, its a no crank issue (100% unique)
if it cranks fast, it's a no start and run symptom.
is the gas old?

if it cranks ok, try, a tuneup., ever do a tuneup this decade?
if it cranks ok and it is tuned (spark plugs etc) then try instant start in a spray can.

watch scotty do a true , no start
classic !

Where is the knock sensor located on the 98 Isuzu Rodeo 2,2 L 4 cyl engine


knock sensor
2.2L 4 banger, most are on side of engine block.
ill look for your.
does the PCM scans tell you its bad? that be first.
its just a microphone, and can be fooled
a bad valve train can make noise and fool it.
the knock sensor has 2 wire,(few things do there)
one wire is yellow, other is green. (clue 2) this usually nails it.
my online isuzu books sux a bit, zero locator.s
but guess what, 3rd google search.
and is where most are, on 4 bangers.
id use a stethoscope ($4) to listen to see if engine has internal noises first, (not ping) but valve train or piston slap, or rod knocks.
why not post symptoms and not just hunts....????

Hey there, Ive got a 4 banger 98 accord with a


this is a TCM (tranny brain) operated, A/T
so scan it, in this old car , it either scans with the PCM or
has its own blink codes, the TCM.
D4 means, TCM is Unhappy, please scan me for lastest news !
the engine too, is bad. but id fix that first because the tranny brain
uses,. 4 engine sensors to run'
so scan the PCM (engine brain) first. fix that first.

alldata.com has all this.. every word every step.
why not read that.?
connect scan tool $9 tools work, and scan the PCM. (ask)
get all DTCs (errorrs) and most them,, here ill also lookup
how to scan your old TCM now.
here is lots for free books on this car.
http://hondatech.info/downloads/Auto/Manuals/Accord/

the PCM when scanned will report 10 unique DTC errors
for the transmission.
and VSS, ECT, TPS, and CKP sensors must be good or
the tranny will fault.

1985 chevy c20 vacuum problems


on this truck the vacuum is pretty basic, im guessing you have a 305 (5.0) or a 350 (5.7), on the front of the engine compartment near the fan shroud somewhere (if it is still intact) you should have a diagram of all the vac lines
you probably have a quadrajet carb, if you are mechanical and patient they are not hard to rebuild

blowing out the carb with carb and choke cleaner isnt a bad idea either, have someone keep it running and slowly run like 1/4 to 1/2 a can down the carb spraying all around

1994 Dodge Caravan intermittent missing, loss of power


Number one and four are fired at the same time on a single wire from the PCM. Look for it to be intermittenly grounding somewhere along the route to the coil. You can wiggle the harness with the engine running to see if you can duplicate the miss. This will help to localize the area where you need to look closer. Look at areas where the harness crosses brackets or lays across areas like the transmission. Long term vibration can wear a small hole in the insulation causing intermittent problems on any circuit. I hope this helps.
