I have an automotive electrical issue I am having trouble with, the injection ECU is reacting to the throttle position sensor too quickly and shutting the fuel off on a trailing throttle too early making the reaction to closed throttle jerky, there was a manufacturer recall on my vehicle in 1992 that was never performed and now the dealer and manufacturer knows nothing about it obviously. I found the information supplied to the dealers detailing the fault and remedy but information is sparse as is my electrical knowledge, the fix involves the fitting of a capacitor between the tps ground and voltage signal wire to the ecu from the throttle position sensor which is just a variable resistor that is supplied 5vDC and varies the voltage back to the ECU between .5v and 4.5v depending on the throttle position, my problem is what capacitor should i use? no details are given in the document. I think the idea behind the fix is that when you close the throttle the signal voltage drops from the TPS to .5v but the remaining charge in the capacitor allows the voltage on this signal line to bleed away a second or so slower as seen by the ECU but i do not have a great enough understanding of electrical components to be able to even start choosing the right capacitor. Any help appreciated.
Thanks
