I have a 93's10 and sometimes when i crank it up it cams like a big block, i know this since i got 40 series FM's no cat. i can rev it a few times and it will go back to regular idle,

it used to do it all the time but after replacing.

fuel pump, computer, MAP sensor, TPS, pcv, spark plugs, wires, distributor cap&rotor,
its doing better but i have the same problem still my last guess is the idle air control valve. but im still not sure, ive had this problem for years.

i hope someone can help.
