When taking off at a light and when shifting from first to second, even to third the vehicle jerks or acts like it does not have enough fuel. The check engine light was on but now it's off. Error codes P0101 and P0102 I replaced Mass Airflow sensor. But I need to check relay and fuses though.

These codes can mean insufficient air traveling through your air filter. So, I would remove the air filter to see how dirty it is. Also check for leaks in the air intake tube between the MAF sensor and throttle body.

I did purchase a K&N intake literally less than a month ago, but all is tightened. The only thing is the O2 sensors I need to replace since I had to get a new CAT because the old one where the flex neck of the pipe was cracked. I end up finding that they did sell just a flexing portion, but I already bought the other part. Which required me to replace the O2s as well. Which I am about to do. Will see if that's the issue.

I noticed the gas cap isn’t as tight as it used to be and I know that will be pulling a code soon.

When you replace the MAF sensor did you clear the codes?

Since I have a small leak in the transmission. It's the inner bell housing seal. I took it to a shop and either they pinched the seal putting it back in or the part was bad and wore out. I just need to do it myself than trusting a shop. To get to the Slave cylinder since its all one piece with the inner seal. And to see what shape the synchro or the gears are looking? Since I know I may had chipped a tooth on the fourth gear. Can you send me the steps for the tranny project I’m going to dive into? Especially the torque specs putting it back together, thank you.
