Engine problems

Hey guys I have a 98 Tacoma with 190 thousand on it it's all stock the problem I'm having is when I step on the throttle after a light or so fourth and the rpms are abt between 3500 and 4 it feels like it's cutting out in between shifts like it feels like it's lack of fuel pressure or something has anyone had this happen to them it started doing this abt 2 weeks ago and today i turned my over drive off while I was entering the freeway and I got on it and it was really bad started chugging and cutting out between 45 and 75 mph and the check engine light kicked on and started to blink for a few seconds and kick off ? Does anyone have a solution to what could be wrong thank you I think it could be a cylinder miss-firing but idk cause at an idle it sounds good

 

I'd search for a thread discussing similar problems, you might turn something up, also try posting in the first gen section, you'll probably get more people who know first gens to see your post there.
