Roots 4 Posted September 14, 2009 Report Share Posted September 14, 2009 every now on then, since i've fitted a pipercross air filter (panel) at any time after driving, cold or hot, when i've been driving and then slow down to a stop, when depressing the clutch pedal, the revs drop, and then bounce back, between 400-1100 (max and min range) or it'll cut out all together.i've cleaned the throttle body, and that's not cured it, i only run it on V-power.i'll check the plugs tomorrow, but the leads and coil are fine, as is the dizzyit's a k-reg (1992) OBD1any help would be awesomecheersChris Link to post Share on other sites

Ben Seabrook 4 Posted September 14, 2009 Report Share Posted September 14, 2009 yeah the ISV is a metal circular bit to the right of the throttle body as you look at the engine mate unclip the sensor and then you can take it out and clean it - use electrical contact cleaner or throttle body cleaner spray it in and make sure the valve moves freely - as for the throttle position sensor not sure how you can check it best bet would be to find another VR and swop it over to see if it makes a difference.

thegoth 5 Posted September 14, 2009 Report Share Posted September 14, 2009 i might also add the car is running rich as fook at the moment' date=' AND it hesitates a bit lowdown[/quote']tbh mate that does sound very similar to the prob I had which turned out to be the throttle position sensor causing the idle issue loss of power and it was running rich as well - as said if you can grab another thottle body or just the sensor of a mate you can bung it on yours and see what happens that's the stage I'm at. Same symptoms even after changing ISV for a brand new one. The TPS of the 16Ver luckily fits the later TB I have hanging around. Only prob is getting the current one off :-(I did notice whilst fettling that if I unplug the TPS it is very erratic and often stalls. However it then runs a bit better when I reconnect it as if the ECU knows not to 100% believe the signals it's getting. When I clear the error the hunting starts again.

Roots 4 Posted September 14, 2009 Author Report Share Posted September 14, 2009 wheres the throttle position sensor then?will any VR6 throttle body fit? or just OBD1? on mine Link to post Share on other sites
Ben Seabrook 4 Posted September 14, 2009 Report Share Posted September 14, 2009 it's on the left hand side of the throttle body as you look at it mate - will need to be an obd1 one mate and there does seem to be several types of sensor although as long as they are on an obd1 body they should be fine Link to post Share on other sites
