Hello friends, I'm telling you about the problem I have with my spi...
Last year I couldn't pass the inspection because I had high CO and wasted a lot of gasoline. Then I assembled the following again:
gasoline filter, cat, water and air sensor, spark plugs, spark plug wires, coil, distributor cover, distributor rotor, vacuum tubes, lambda sensor and thermostat at 88... it has been going very very well until a couple of months ago when it started to give big jerks as if you step on the accelerator like pressing the drum pedal. When you release the gas it stops and has a hard time starting and when it starts the revolutions stay low without responding.
Now I have installed another tps, accelerator pedal switch and new crankshaft sensor and it is still the same... The fuel pump works and has flow, I don't know what else to do, what else can you tell me about this? I'm desperate! thank you very much friends!

Even you say fuel flows, i would check fuel filter and fuel pressure!

Have a look for an interface ,download one of the diagnostic softwares and make a logfile.Publish it here.
