I have a 93 S10 2.5l 4 cyl it starts and after i cleaned the throttle body it idled almost wonderful but when i shift from park to reverse or drive it jerks and bogs down and dies. I also changed the

Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

Try cleaning the idle speed control valve and the throttle body, then disconnect the battery negative and let stand for 5 minutes and try it.

PO300 codes are cylinder misfires
Lot on the internet you can study
Usually a failed coil but not always the one
you get the code for
May have to walk a new one from cyl to cyl
Did you create a vacuum leak

I would clean the idle air control valve its more than likely stuck open.Its located on the throttle body just like the TPS.

i think i would go back and make sure everything is hooked up at the throttle body. will engine rev up when in park ?

Problems with Nissan 2005 Altima include-Crank shaft position sensor with ECU reset, ECU Factory reset from Dealer, Low Fuel pressure requiring fuel pump replacement, Replacement of ignition coils causing misfire during start-Catalytic Converter Recall-Oxygen sensor on exhaust-Leaking Valve cover gasket-Radiator failure due to plastic top & Bottom (Constantly adding water to reservoir?)

This is idle air control error and with luck should be easy and cheap to remedy. Basically you need to clean out the interior of your throttle body and throttle plate thoroughly. Disconnect the air ducting between the air filter and the throttle body. Use a cloth and WD40 spray and clean the throttle throat and plate. rotate the plate and clean behind. If you have idle air control passage leading off from the throttle wall interior you will find the idle air control valve mounted on the side of the throttle with an electrical connection to it. Remove the connection and unbolt the valve. Clean the valve interior and the passages in the throttle leading to it. Reassemble everything in reverse order and that should be the job done

check and clean your IAC valve, clean intake/throttle body. is your "service engine soon" light on??

with 117000miles buy a new ics valve and replace,its easy 2 bolts 1 gasket 1 wire to unclip.when you have the part in hand look for it on the throttle body near the black intake hose from the air filter.

Check the engine mountain rubbers ,, one or more of them is broken and needs to be replaced.

pop the hood, start the vehicle and move it from park to drive to reverse with the brake pedal down and you will see the engine moving. the broken mounting rubbers are the cause for this.
