i have misfire while in drive. it does not misifre when i have it in park or nuetral. only when its in drive. it gets worse the more throttle you give itand eventually if youve got enough throttle it starts to flash the ses light. i have gotten codes p1810, somethign to do wiht my transmission pressure switch, and a p0101 code for my map or maf sensor.

That's the way all misfires act. Check the MAP sensor and the vacuum supply to it.

Slowly apply vacuum with a hand vacuum pump to it and you should get smooth declining voltage from just under 5v down to about .5 volt at full vacuum.

well my dad insisted tha ti disconnect the battery completely for 5 minutes in an attempt to somehow reset the computer...fail. took it to autozone and checked codes, got random misfire and a high voltage input and low voltage input for my MAF sensor....is there a way to test my sensor ive already cleaned it with the rubbing alcohol and it didnt do anything for it. and is there a way i myself can fix it, id much rather fix it myself or attempt instead of spending a $135 with the $85 core charge. if not yay for money pit!.... thanks for all the help peeps

How does erasing the codes fix anything?

he thought that maybe it would reset some sensors and that the readings would change somehow..i tried to tell him but he still insisted.

Sensors don't reset. The adaptive strategies are reset to zero and start over but they will go right back to where they were if nothing has changed in the engine.

okay so the reading coming from the maf output wire is going to be measured in what exactly? the test i read about was for gm specific mafs and the sensor in the pics was the same as mine too.

I thought we were talking about a MAP sensor here. You are probably right
