SOURCE: lurching at low speed take off

I would start by cleaning the inside of the Mass Air Flow sensor, dirt gets on the sensor element from the air going through and causes these kinds of problems, a company called CRC makes the spray cleaner for MAF's, any good auto parts store will have it, the MAF is located in the air intake hose to the engine. Another thing to check is the throttle valve and air bypass idle speed control valve for sludge, use the following procedure I have written to perform this.
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

You may need to have tyres balanced and wheel alignment done.

SOURCE: on a 96 toyota tacoma, coil packs are new, plugs

Is there any check engine lights on?The throttle position switch could be a problem,but so can fuel pressure.Fuel pressure is what I would check.Battery voltage and charging voltage needs to be checked,Battery voltage of course should be 12 volts.The charging voltage should be 13.65 to 14.25,and the battery cables cleaned real good and shiny.Does the vehicle start good,or drag when starting?See if auto zone will read the codes for you,and tell you what they are,but don`t purchase any parts until you come back to this site to see what the codes can actually mean.If the o2 sensor showed lean,then it is possible that the fuel pressure is low,fuel pump replacement will be a must. I hope this was helpful,but need information,so do these things and return to the site.thank you.

Why does engine run rich at times under acceleration?

not enough detail
to get an engine to accelerate , the air /fuel mixture is moved to rich in accordance with engine rpms
the more rpms the richer until the peak rpms are reached
( accelerator pump-power valve in carbies and ECM settings according to accelerator position
black exhaust smoke in diesels
so if you press the accelerator slowly then the air/fuel mixture is altered constantly in relation to the pedal setting
If you floor the pedal then it moves to rich and you get black exhaust smoke until the air mixture is again in balance

Truck want accelerate over 35 mph black smoke comes out and skip 1998 international t444e 4700 7.3

missing can be from faulty injector tips and or low fuel pressures
Low fuel pressure can be from a blocked vent pipe on the top of the fuel tank not allowing sufficient fuel through to maintain pressure to the pump.

After braking or slowing down acceleration stall

Check fuel pressure. Parts stores rent a fuel pressure gauge. If fuel pressure is low, check fuel pump and filter.

2001 Toyota Tacoma keeps stalling on start up.

Check the battery cables. I had the same issues with my 96 tacoma, The battery cable connection at the battery can be cranked down but still be loose. Hard to explain, doesn't make sense, but just check it out.

I know you might not want to take any advice from an automotive student, but did you check your catalytic convertor? We went over this in class last week and all the issues you are having I had with my same year Tacoma. Once I replaced my cat it runs fine now.

I wander about my engine; its new overhaul the problem is when its cold the idle fine but when i accelerate the rpm goes high and hard to back at normal idling, the mechanic can't pin point the trouble,...

Black deposits on the spark plugs are a sign of too much fuel getting into the engine. Have him check that the air filter is clean. This, in my opinion,sounds like the fuel pressure regulator is faulty allowing too much fuel pressure to the injector rail. Have him check toh fuel pressure regulator on the fuel rail. This is easy and inexpensive to repair.

My 1997 Jeep Grand Cherokee Laredo is starting to have a ''slight'' hesitation after I shut it off and re-start it again. WHen I accelerate at first it hesitates a bit. I let off the gas for a few seconds...

A slight hesitation after engine shut off due to engine running rich meaning not meeting golden air:gas ratio of 14.6:1 so fuel residue in chamber continue to burn for the last moment. The same rich fuel problem that was why you had to let gas off during acceleration. Need to Check out the O2 sensor Check out MAP sensor Good luck

Engine is skipping when accelerating

You only have 4 so better just do a tune up and change the plug and wires, but one at a time so you don't get them crossed when re-installing the new plugs and wire.
Use Platinum plugs since there good for 100,000 miles which mean less maintenance, and double check that the spark plug boots set to the plugs when re-installed.
Run some fuel injector cleaner through the gas tank for about a week to to clean out your fuel system and hope fully the skipping stops.
If your going to get all the goodys at Auto Zone, have them scan the car for any DTC codes since it's free and see if there are other issues that is causing the skipping like a bad signal from the MAP sensor ECT.
Good luck and keep me posted.

Catallytic converter might have gone bad??

What you smell is the convertor working to burn off excessive unburn fuel in the exhaust. That does not mean the cat is bad, but your engine is possibly running too rich on acceleration. If it only happens on real hard acceleration, its normal. If it happens on just normal acceleration then you may have a too rich condition witch will eventually harm the cat. Possible problems are a faulty MAF sensor, partially cloged or internally leaking injector or high fuel pressure.
Have it checked by a competant technician if its a constant problem or the check engine light comes on.
