Recently I had a new TPS/ CPS/ Temp Sensor (blue plug) installed on my 88 SETA 2.7i. It was fine for a couple days. Now its bucking / stalling only in 1st & 2nd gears when it is at operating temp, video included.. Its perfectly fine at freeway speed or above 2.5k it works fine but will sputter below 2.5k.
I've cleaned my ICV, checked my fuel relay and fuel pressure. Its not a vacuum leak otherwise it wouldn't hold idle. I know later models only have 1 CPS and I'm pretty sure I didn't get the wrong one but I couldn't get my hands on a bosch one so I got this VEMO one. It was a bit different from the other CPS I had it was fully exposed where as this new one had a hole on it. I included a picture below to show the 2 different ones. I'm hitting a wall here and don't know what else to do.
