My Car Being Different.

[borodaz]

when my car is warmed up and sat in neutral, every so often (between 1 and 2 mins) my rpm starts to fluctuate from 800 to 1200 asif the car is revving itself a bit. this has never happened before in my car.

i looked in engine bay and the car seems to make a click then the fan turns on, but the fan only stays on for about 20 seconds. car seems a bit funny when setting off and when changing gears.

could my clutch be on its way out ? or could it be the little problem with my mass air sensor as the wire is just pushed in and taped to make conection ?

help please lads

have a similair problem - although it aint done it for a few weeks. does yours also drop down in revs too? that sort of thing often indicates a leak on the intake - when i had to get the service book stamped me mate sprayed some carb cleaner around the intake and there was a slight pick-up of revs when it was sprayed around the stud nearest the throttle body - indicating a leak. took it to toyota and instead of using carb cleaner they sprayed brake cleaner(not as combustable) around the intake and said they found nothing?! someone on here had a similar prob - one of the lads with a compressor - and i sent him a pm and he said toyota had changed the inlet but wasnt 100% sure if they changed the whole unit or just the gasket - so as i got no joy from mr t was gonna change the gasket myself and fit a decent one to see if that sorts the problem out. havent managed to get round to it yet as been having a bit of a headache with the misses smart car my concern is the leak is after the AFM so the car is probably overfuelling slightly which can lead to other problems. oh ye - when i took it to mr t they cleaned the AFM - like if it was that simple i would have took it to a garage!! - and it made no difference. i would check the AFM first though. let us know if you find the problem as i think a few do it.

Is the air con on or off?

[borodaz]

what is the AFM ? car was due a service at 20k its now at 20.1kmiles sorting some cash out to get service booked hopefuly they can solve it.

air flow meter. mine started doing it at about 22k - been 3 different dealers and they cant sort it, yet me mate who works for a decent independant diagnosed the fault immediately. another mate of mine is an mot tester and i was talking to him about it when i had me mot and he said when the engine starts "searching" its normally a leak. but what do they know compared to mr t!!

[borodaz]

air con is always off in my car, aint had the car through summer yet.

so do i need a new air flow meter ? is this the air flow meter that sits on the induction kit ? my induction kit silver pipe (typhoon) is getting fairly warm/hot.

If it happens in my car i just blip the throttle a few times and i evens out.

you shouldnt need a new afm - just clean it and see if that sorts it. blipping the throttle often returns it to normal but doesnt answer why its happening. does your car drop in revs too? mine drops to 5-600 revs then rises to 1200 before settling back. i've been meaning to change the inlet gaskets - still got warranty and i have to sort my own car?! be interesting to see what your mr t comes up with. try the carb cleaner before you take it in - didnt help me but you might have more luck.

Mine does that too B)....never really worried about it..

ive had that before, i put in some 99octane fuel in and sorts it. dunno if that helps

[borodaz]

back to this problem, ive been driving the car and it seems fine running wise, but it still fluctuates and i dont like it, car seems to warm up quicker than before too. as someone asked above yes it does drop down to about 700 rpm.

i did once put £10 of unleaded in about a week ago and as i set off i noticed it was being funny and thaught nothing of it and never checked for fluctuation. before this ive only ever used v power and i have filled up with v power since i put the bog-standard un-leaded in and it still is fluctuating (not as bad as at first) i must say.

maybe my tank needs flushing with more v power and a ecu reset ? ? ?

ive stopped hitting lift everytime im out in the car now as im scared about damaging engine. going for service on saterday going to get it pluged into the computer see what comes up :) in the meantime im being a lift virgin haha

[ae102]

had my car plugged in at 2 different mr t's. as the engine light wasn't on it didnt throw anything uo :( have you tried spraying carb cleaner around the inlet to see if the revs rise? mine hasnt done it for a while - it does tend to be worse when the weather is warm which makes me think its a leak. i hope your mr t knows what it is as it seems a common fault. do you get any hesitation on acceleration? i've used optimax/v power since i got the car two years ago.

Dont let it put you off hitting lift....these engines were put in Lotuses and track cars so they are designed for a good thrashing.....

If anything it may not like you anymore if you !Removed! it :D :D

Car is probably warming up quicker due to the warmer weather....

[borodaz]

aint done the carb cleaner trick yet will give it a go when ive got a day off, maybe it is due to warmer weather all together.

dont know about hesitation in acceleration if so its very small i can hardly notice.

just been to gym couldnt help myself hit lift lol still feels as quick though.

[cabcurtains]

My car gets a little hesitant when the weather warms up, I've put it down to the induction kit, as all the other cars i've had with these fitted have done this, its most noticeable when pulling from 2nd gear at low speeds. The engine bogs a little until some more cold air gets in.

[blackcts]

Mine idles perfectly when warm...sits at 900 and doesnt move...but if the car is cold and warming up (for example the temp gauge is 1/3 of the way up) sometimes the revs can drop to say 700 then rise again...

Anyone else notice this

Just a thought...wonder if its got anything to do with the k&n panel filter i fitted???

help please lads

ive not had that problem with the cts but my first car was an old mk 1 n reg punto and i suddenly noticed that some times i would be waiting in traffic or at lights and have my food away from the gas and the car was strangely revving its engine for a few seconds then dropping off and after a second of normal it was revving up again, the car didnt have a tachometer so ive no idea of the exact RPM. eventualy i got it sorted as one of my dads mates owns a garage and it turned out that the fuel injectors where simply dirty because i had been running the car with hardly any fuel in it and spent a lot of time in the red and it had sucked all the crap up from the fuel tank and was giving me funny revs when idleing.

i dont know if this is the same as what your cts is doing but it sounds quite similar to me.

hope ive helped

u say yours idles perfectly when warm and it sits at 900, thats strange as when mine was siting idle perfectly it would stay at 800 at not change at all.

rimpson, sounds similar dont know what to do as i dont have any spare cash to take it to mr T and they will charge lots. was due a service today from a family member at a jennings garage but didnt happen, may take it to toyota when got the cash as soon as.

[Rimpson]

sounds like a plan, hope you get it sorted soon mate and it doesnt cost you a kidney to pay for it :P

Maybe it was 800...was just off the top of my head...someone raised a point about petrol, i always use Sainsburys fuel.

[marty32]

borodaz u mention car is warming up quicker than usual! check your water levels and waterpum i had my water pump done at 34000 miles

mr t at rmb has a diagnostic fee of 80 notes im told the 4th year service over there costs 220 quid all in i got mine done there when i had it

[borodaz]

could be another option i still aint had time to check my car out and take it to the garage, working all the hours god sends at the mo.

still keep driving the car about hopefully wont be doing any damage.

[marty32]

pop bonnet up n check engine coolant if usin lot could be water pump
