Midnight-Runner Posted October 16, 2012 Share Posted October 16, 2012 Hi everyone,my name is Lana & im new to the site...im having a few problems with my 1998 ® ford escort 1.8 gti. It has recently passed its m.o.t & had a full service including gear box oil change.When i start it up it ticks over at around 900/1000 rpm but like all escorts it breathes so the needle does fluctuate. My son recently changed the idle speed control valve as the car was up & down on the revs without me touching the excellerator,this seemed to solve my problems up until the service was done. My problem now is in the morning when i start it up (warmed up) & try to pull off,the car seems to have no power in 1st gear (feels like holding back) 2nd gear it jumps & judders like its running on kangeroo juice (excuse the pun) 3rd gear taking it nice and slow seems fine,but on excelleration will jump & judder again...after a while it seems to settle down & clear itself & it runs fine.I have once experienced this in 5th gear trying to excellerate up from 60mph on the motorway & it frightened the life out of me. Someone suggested it could be the throttle housing on the ecu...remember guys im female & really dont know too much about these things.Before going out and spending fortunes on a new one i thought id ask your advice first.... My son is learning mechanics & knows a few things about cars,he is good at taking bits off & replacing them but still has a few problems diagnosing faults. Any help or advice would be greatly appreciated...thank you in advance Lana x Quote Link to comment Share on other sites More sharing options...
vinnyvangough Posted November 6, 2012 Share Posted November 6, 2012 Throttle housing on ECU? ECU is and electronic brain located in the passenger footwell so nothing to do with a throttle housing. Sounds to me like it could be a Llambda sensor playing up or a coil pack breaking down Quote Link to comment Share on other sites More sharing options...
