Hello, I am new to these forums and in need of some guidance.
I have a 1990 ford ranger with a 2.9l It seems as if once I start driving the truck for a few min til it gets about normal temp it starts to do this "surge" in the rpms. It idles fine far as i can tell at aprox 800rpm. I have replaced the following: all new plugs and wires, new coil pack, new distributor and verified correct firing order, TPS sensor (also adjusted), IAT sensor, new throttle sensor and also a new throttle.
Im kind of lost now, ive been replacing and replacing and everything that ive done has helped performance of the motor for sure but hasnt fixed my main issue of the sputtering.
I made a short video, but you can kinda see what im talking about with the RPMs spiking
