zorgman Posted January 22, 2007 Report Posted January 22, 2007 right the sorry tale goes on with my 2.0L galaxy heres the list and readings off scanmaster.new leads and plugs, oil filters etc,o2 sensor pulsing nice between .08 and 0.8 so i assume thats okmaf showing 3gs increases when reved,air temp okwater temp oktp sensor ok.infact not one fault code showing and all the sensors are reading fine going up and down etc. heres the fault lack of power the odd jerk of engine ie misfire when accelarating in 5th, a flat spot from idle pulling away and one ive been thinking about may be a problem. when driving along and changing up or down gear the engine ""hangs"" at the same rpm then slowly drops is that normal.the only thing ive got left is the actual exhaust system as ive swapped out off a known good source all the sensors etc.egr valves fine all the vac line replaced cleaned every thing in sight so im now stuckhelp me please or the cars going and getting another xantia 1.9td Quote
Guest mcyoungy Posted January 22, 2007 Report Posted January 22, 2007 Sounds more like an inlet air leak to me. Quote
Guest wolfie Posted January 22, 2007 Report Posted January 22, 2007 throttle hanging between gear changes? possible sticking ISV, throttle position sensor? air inlet leak as suggested? Quote
zorgman Posted January 22, 2007 Author Report Posted January 22, 2007 good clean ivs changed that as tickover was at 3000rpm its now rock sold at 975rpm, tps shows as reading proper sits at 16.9% at tickover and responds to throttle going up and down. have cleaned everything that can get gummed up ie maf, egr etc so ive ruled that lot out. will recheck all the hoses. one thing to mention car is very thirsty ie Quote
seatkid Posted January 23, 2007 Report Posted January 23, 2007 o2 sensor pulsing nice between .08 and 0.8 so i assume thats ok AFAIK O2 should be 1.00 +/- 0.05 Your car is running way too rich, possibilities are air intake blockage (air filter) - exhaust system blockage (cat) - fuelling system problem.

zorgman Posted January 23, 2007 Author Report Posted January 23, 2007 well its the cat getting chopped wed see if that works,i thought that the o2 sensor is pulsed and that mine at 0.2 upto 0.8 was fine as its constantly pulsing up and down, the fuel loop is ok for it. one thing just noticed is that is 2deg c here and intake temp says its 19deg c so changing that morrow as well just in case.
