1997 engine missfire
#14
oops. i have no idea what engine is in that car? not me but its no G16B 1996 and newer
does the hood have a (look up underside of it) have a white sticker with vacuum routes, does it say USA federal , USA calif or Canada fed.?
in 1996 then added the teeth and all have the same teeth count.
maybe this is a 99 engine,, on the left side of the block is the SERIAL G16Tnnnnn where T is the year.

so I had a look at the wire running to the sensor, someone routed it up against the alternator, could be picking up rfi from alternator. 2nd issue,
it is shielded and must be grounded , that shield in the proper way.

it's a shielded cable and the braid down at the plug has been cut and folded back over itself about 3 inches up from the plug. could have been an rfi issue all along. should the braided shield be grounded at each end? (no,, because that forms a bad ground loop, its grounded at the other end)_

and I also believe the 2 wires should be twisted not parallel, or maybe that's what the braid does. (yes, twists are cheap cables , with no braids) (like cat5/6 cables,)
not sure how the wire is supposed to be routed but ill keep at as far from alt as possible.
The cable is shielded, the twists can help but are redundant to the shield, just trust the shield to work. and only 1 ground. never 2.
2 grounds create a ground loop and becomes a noise generator via ground currents.... the harness pages, in FSM show this clearly.



all 96s, round down the left (drivers perspective) timing cover.
if the belt was slipped and is now corrected, then the dizzy is now wrong, .


year decodes off my page.
T= 96
V=97
w-98
x=99
y-2000
1=2001 ect for engine codes. same with VIN year codes.

this is the only valid COG 96 to 98, im doing research of 99 plus (later this AM)
this and only this cog works with your ECU, do yo have your ECU P/n? maybe they are not a match>? dash 71E31? or 71E01?

last , does your ECU MATCH this, includes canada cars.

ecu charts, PDF reader needed.

"the one on my sunrunner has at least 4 times as many notches for the csp."

WRONG !

Quote:the one on my sunrunner has at least 4 times as many notches for the csp.
CKP,
suzuki makes 56 engines. so mixing parts can be , a problem.
im in the EPC trying to see if there is any 1.6l variants . sure there are DOHC motors, with chains, but only the ESTEEM variant , matches 52G01 cogs.
Im sure you have a 52G cog. (tone wheel) (so , wrong engine, wrong ecu, or wrong cog)

the correct cog is -75B01.
see correct tone wheel here, works up to year 2004 for G16B engines.

I looked at all 1.6L and the only cog change the
that has cog (tonewheel) dash 52G01 number. SY416 body, for Esteem cars.
what CAMI used for engines in a Sunrunner? i bet nobody knows.

but the engine serial, and ecu p/n and the under hood sticker, do help.


my new engine. (new crank, used block, and new rebuilt head.)
http://www.fixkick.com/engine/97-motor-p...ge_58.html


is your Throttle body a left hand side draft body, that is , it mounts to the left plenum , like this photo shows

this is what all 1996 , G16B engines look like in USA and canada, Suz , GEO or from CAMI, (can't speak for sunrunners, rare too)
watch out for other folks, swapping short blocks and not paying attention to the crank cog.

on ours the moved the back washer the the the cog in 1995, then in 1996, the cog. (OBD2 TONE WHEEL) it has only 6 teeth?
and stayed that way even past 1999 on 1.6L SOHC.
I can not see your motor , so my guessing is WIDE SCOPE.
does that sun runner have an RPO tag. open glove box. see huge tag? and those numbers all state what was in the car day one, build wise.
ALL GM /GEOs. have that , same with Pontiac. and can be decoded, using my RPO page.
