when i start the engine and remove an ht lead you would expect to see the spark jump on the part of the lead that connects to the spark plug but on my car the spark jump happens at the distributor cap end of the lead, the sparks coming out of the rubber insulation and hitting the distributor holding...

so can you tell me this then. if i do the tps adjust again and then adjust the idle air screw so that it sits at 750rpm the car should be setup ok. because it was said that the idle air screw has to be set correctly so mine should be at the optimum setting if the tps adjust is done correctly. but it...

right i have just cleaned the sparkplugs and put a new filter in the airbox and the problem is still there. the idle sits perfectly at 750rpm with no movements up and down. but when i press the accelerator pedal lightly it makes the revs drop a little before they go up and the power below 4000rpm se...

soz ppl. noted for the future. ill just keep adding to the 1 topic and not start so many its just cause i didnt think i was getting a reply. yeah its only a half a second dip hardly noticable. im glad its not the idle air screw. cause everything is ok at idle and at everyother rpm. so just normal i ...

what way should i turn the screw to get more vacuum cw or ccw.

well i will try and remember that. thnx. so what can i do then put the car in diagnostic mode then start the engine ang adjust the screw. but what way would u suggest? and when i do turn the screw will the tps need adjusting again? dont know where the original setting was. thnx for the info

well i put the car in diagnostic then done the tps adjustment and then adjusted the screw till the idle was at 750rpm the took the car out of diagnostic setting and the idle sits perfect no hunting or anything. just a slight dip in power at 3900rpm but nowhere else. what could cause this problem?

is it normal for the v6 engine to be hesitant when cold?

does anyone get a very slight power dip at 3900rpm jst before the vris kicks in coz my car has started to do that but is fine everywhere else. i also done the tps adjustment and the car is much better and i adjusted the idle air screw to 750rpm and needle doent jump up and down anymore. could this b...

does the screw on top of the throttle body control air/fuel mixture? or just the idle speed. coz i adjusted mine and the car seems to have lost a bit of power but only between 3700rpm and 4000rpm just a slight hesitation.

my car has started to idle funny so i adjusted the screw on top of the throttle body now the car doesnt have the power it used to. can adjusting the screw f**k up your engine performance? also the 6 spark plugs were sooted right up but that was before i adjusted the screw. the engine sometimes has a...

can someone please help? my car when accelerating in the first three gears goes really fast then when i take forth gear to 7000rpm (takes a while) and put it into fifth gear the car will hardly accelerate struggles to get to 110mph. but if i take it to say 5000rpm in forth gear and put it into fifth...

i turned the idle adjustment screw to lower the idling tjey still stuck at 1200rpm but the car now doesnt feel as fast at accelerating and cant get it back to the factory setting please help

the problem is when i first partly touch the accelerator the engine bogs down for about half a second then revs up fine but if i touch the accelerator pedal hard the engine revs ok without any bogging down please help! also when i get to 6500rpm the engine seems to lose a bit of power but it still r...

could the problem be fuelling related? i dont see how cause the car pulls fine in the first 3 gears at high rpm. just at high rpm in 4th and fifth the car doesnt pull quick at all. it almost feels like the car is dragging but the brakes are ok. could faulty ignition leads and distributor cap cause t...
