Missing oil pressure switch?

[fixkick]

As usual you are the man!

I have her running way better than she was! No longer losing rpms uphill. Holding temperature.

I still have a few issues though. It's "dieseling" more than it should when i have it warmed up and let off the gas coasting downhill. I smell exhaust when this happens even though its not as fuel rich as before when running rich from being too cool. There are holes in my floorboard though and the muffler doesnt go all the way to the rear of the vehicle and actually have the tailpipe right before the front of rear wheels so I could just be smelling it.

BUT the catalytic converter rattles when i start up. I looked at it while running warm and it seems cause the piping to rattle like..the top of the y piping near the manifold doesnt rattle..the muffler doesnt rattle but it just looks like the cat converter is causing a rattle emanating out both sides from that point.

its only partially clogged for sure..my question is:

Do i replace JUST the cat and pay $100 for it plus however much i have to pay the muffler shop to cut and weld it back on OR do i bite the bullet and pay $250 for one that is prefabricated and includes the y-piping..and is ready to bolt onto the front pipe and muffler? The y piping is rusted and may have small holes..i need to inspect more.




LAST QUESTION: regarding the bogging down and the exhaust.. Do you havr any tips for cleaning the Egr valve? I want to pull and Clean it as i suspect it may be what is causing my bogging down issues because these issues DONT HAPPEN AT IDLE OR LOW SPEED NOR AT HIGH SPEED..I CAN ACCELERATE THRU IT.

UPDATE: all else is well and all repairs and checks done either fixed the problem or were dead on already! I still have a little cleaning of grounds to do..but anyways: when i changed my thermostat and pcv valve..i checked the fuel injectors like u said and the screens were pretty dirty But thank god no leaks so I dont need a new injector. Thank you so much for this advice.

U have literally talked me thru fixing my car completely: saving me thousands of dollars in the process . i entered this not even knowing how a lot of these systems even work but now i do! Thank you so much. When i bought this car I did so because I knew there was this site to help with any issues. Boy was i right!

To anybody reading this who is thinking about buying a tracker or sidekick: if ur willing to do the work..it is worth it!! And lets just face it..they are sexy little trucks that perform.in every way advertised with quality and reliability that people are always looking for but usually dont get..especially with the 8v 3sp 4x4 version i have- ZERO complaints. I love it!!!

not sure your meaning on dieseling
on gas engine that does that , that is PINGING or more accurately Detonation, and piston destruction mode. (lean burn or  super advance spark or dead EGR)
EGR cuts HOX and also ends all PINGING on this engine, a 2 fold fix and 3rd fold cuts NOX so the CAT does not wreck its 3way cat NOX feature .
your cat is dead, if you smell fumes in the drives set window closed that means holes in the body of car, and bad cat and or holes in the exhaust pipes,,etc.
windows open smells is bad cat. and or holed up front headers.

A dead cat , with those short pipes will stick like hell.  and CO is a big danger on cars,  that is why the tail pipe is on rear end of left side of bumper.
CO is man killer and guess what all sidekicks love to make CO for sure in limphome mode or way too high fuel pressure.
cars are designed to be safe when engine happy and not happy and dumping lots of CO ( carbon DiOxide  the silent killer of man) NOX is bad too burned eyes.
all monolithic  CATS (means not gravel/pellets   type seen on some toyota's) the CAT inside is BRICK an honeycomb brick and all old cats break up inside
and the rattle as they do that and then break more until the brick is GONE Totally.  all do that this old, it  is not new. all do it.
some rattle so bad will  make any driver go batty. for sure, even cruising noise.

you only have 2 choice,  a full header back kit . Like what
or run on cat at all. but no holes allowed, and pipe goes full rear. for no stink parked at stop signs. nasty stink it will be. (like 1960s cars or older)

with no CAT or it is gutted or blown out or rod'ed out. fully the EGR is now 100% dead, if you like that ?

if not smog tests , many just run no CAT, sure the exhaust is nasty full of NOX,.
this car is sold on south sea islands (example 1) CALLED the JDP, version no CAT no EGR, at all. and different ECU sure.


EGR cleaning, why do that when with no CAT or blown out, the EGR is now dead
the EGR valve uses CAT back pressures to do its job on this car, no cat no egr.
no need to clean a dead EGR ever, due to modulator off line stated, CAT gone or blown out.


wow if I saved you 1000 bucks, that makes me so happy, love to help on old cars i do.


ever put marbles in a tin can orbucket and shake it , and hear that rattling sound that is sound of PING'ing
do not allow that to happen.  
EGR ends ping but better fuel does to ,high octane, with EGR working low octane is ok.

if no working EGR , try the better fuel or run some retarded spark
if hood label shows, -5 Degr. BTDC static timed drop to 3 deg. or 2. see of ping ends only if it is.
