My 1986 Nissan Maxima engine sometimes bogs and runs rough and I can't accelerate to more than 10 miles per hour. After my 1986 Nissan Maxima V-6 engine with 88,000 miles on it warms up and is dri

Clean throtlle body,change air filter.

Clean or replace EGR.

you may have a restricted catalytic converter plugging up exhaust flow and bogging down the engine. on the vq35 engine there are 2 precats located right under the exhaust manifold and it is then plumbed down the downpipe and into the main catalytic converter. i would remove the downpipe and inspect the the condition of the catalyst.

Check the throttle positioning sensor and the transmission, it sound loke the sensor is givving bad information to the computer whis is cutting the engine when in gear, this might cause the transmission to break its syncro plate if it slamms in and out of gear.

most likley a ignition coil is failing, is unfortunatly common for the A33 maxima. these engine have 6 coils, one for each cylinder. the only way to work out which of the 6 is the faulty one is to remove the little cover over the front bank of spark plugs, has 4 allen key bolts, then you can see the front 3 coils and the rear 3 are inbetween the manifold pipes. each coil wiring will have a button/leaver on the connectors (i think they are green) and if you push this in will release connector.
when the engine is missfireing unplug one coil at a time then reconnect after. if the engine runs worse that coil is working. if you unplug 1 that makes no change, that is the the one thats not working. replace the coil and the spark plug.
do not worrry, there is only 12volts at these connectors, not spark plug voltage

MOST LIKELY A DISTURBUTOR PROBLEM. EVEN THOUGH IT FIRES THEY TEND TO GO BAD AND MISFIRE UNDER ACCELERATION.

Every answer here is wrong. This has been driving people nuts for 15 years. The problem is the engine wiring harness which has a bend going past the right strut tower, Nissan had a service bulletin on this in September of 1999, Google it, it's in pdf.
