Default Camry 2.2CI Engine Stumbling

Hi....I have a 1995 Camry with a 2.2 4 cylinder & 136,000 miles. All of a
sudden the engine started to stumble from the start. Also it stumbles at a
steady RPM. However it seems ok at high RPM but can feel a noticable engine
rumble traveling down the high way. I pulled the plugs and checked the
spark (all checked good). However, one plug showed soot as opposed to the
rest. I checked sensors associated with the fuel system but they checked
good. Can this be a fouled injector?

I still need to check the Emissions side of the house. Any help would be
appreciated. THanks

I would look for a split or disconnected
vacuum line first. Wonder how you
checked the sensors..Doubt its an
injector, it would not "rumble" and
it would not happen all of a sudden.

Thanks, I followed the repair manual and used an Ohm Meter to check
resistances.

Would a clogged vacuum port in the Throttle Body cause this? I am asking
because I followed a repair manual for one of the checks and found a weak
vacuum when above idle.

I just had a similar problem, it started fine till hot then missed on
one cilinder. I replaced plug wires , it fixed it. My 3 yr old
aftermarket wires were crap.

I find buying most parts aftermarket to be suspect, For years my car
would not get warm fast enough, I just replaced the thermostat with
Toyota and what a difference. I tested the old thermostat it was fine
but the gasket was smaller and narrower letting water bypass. I should
have known when the mechanic said he had to use a lot of silicone
sealant to keep it from leaking. Many parts are just worth the extra
Toyota money to be sure your car runs right and the parts last. The
parts stores answer to this was "we get them as cheap as we can"
Problem is, no quality control, so who suffers, the consumer, us.

Aftermarket wires usuallu are. I learned a long, long time ago, use genuine
Toyota (er, Sumitomo?) wires. I did a complete tune up using off the rack
parts, and the car ran like crap. So 3 weeks after I did the tune up I
bought real Toyota wires and only got 150,000 miles out of them.

Would have thought I had learned, since on the same car i did a tune up with
genuine Filko parts (they're out of business, right? and the rotor arm
blew the brass contact into a dozen little brass balls in the base of the
distributor. Genuine Toyota after that...

Certainly possible.
I've got the 1994 Camry 4 cylinder.
Recently changed the idle air control valve, and followed the procedure
in the Factory service manual for removing and cleaning the throttle
body with carburetor cleaner and compressed air through the three
vacuum ports that feed the EGR modulator, located just beyond the
closed position for the throttle butterfly valve.
The first port has a very, very tiny orifice. Gunky brownish black
residue came out when blasted with compressed air as shown in the
diagram.
That was at 126,000 miles always using good quality name brand
gasoline.
However, I may also have had incomplete combustion for some time,
similar to your comment about a sooty spark plug. One of my original
plug wires had been shorting to ground inside the spark plug tube where
it was not visible.

one plug showed soot

That's your clue. You need to correct the problem in the secondary
ignition system.
