hey,

i have a 98 honda civic 1.6i es automatic, when i first got it it was fine but then every now and then (mainly when first starting up from cold) it makes a sound like your pushing the gas pedal down then up down then up if that makes sense. i was reversing up my drive and it was juddering and just about to stall (thats the worse it has been). recently ill be doing around 30 and i can here the sound that i mentioned earlier so im not sure whether its getting worse. it doesnt happen all the time but mainly when its cold. its terrible moving off i.e from lights etc ill put it in N and engine seems fine every now and again the revs will really drop gradually but never left it long enough to see what happens, but when i put it into D it moves off juddering along as if im pushing the gas pedal braking gas pedal braking far from smooth has anyone any idea of what could be the problem? as i said its not all the time sometimes it can be lovely moving off but alot of the time it isnt and i look like a **** lol.

Thanks in advance,

Dan.

 

how many miles on?
The first and the cheapest thing to do is the ATF Z1 (use Honda only) flush- I bet you it never had a drain and fill. you will have to perfom it few times every 3k for a complete change.

 

its got 76000 miles on it. i have no idea what transmission fluid is in there at the moment, i bought it Nov 09 and was on my drive for 8 months regularly started up but not properly driven untill August time. how much is that Z1?

 

$6-$8 per quart...each time you do it it may take up to 2.5qt- the vehicle must be level and the car warmed up.

Let's hope nobody fed her wrong fluid before. Hondas are finicky that way.

 

idle jumping up and down...clean iacv on back of intake or air may be in cooling system

 

Maverickdc, if indeed you have what's described as "jumping idle" then start addressing the problem as hatchet_honda suggests ^

 

thanks for the suggestions guys, cleaning the iacv should i use the liquid additive in the petrol? or should i take it off and spray it?

 

Definitely start by cleaning the IACV and bleeding the cooling system.

Any CEL codes?

 

no dont have any codes sorry ron. would you be able to answer my question whether putting a liquid additive to clean injection or just take it apart and spray it?

 

Remove it for cleaning.

 

ok cheers think i was thinking of something else then lol would it be worth cleaning the injectors as well?
