maybe the fuel filter

 

[modsHXcivi]

I agree with Snoop ....check/install new fuel filter...


when was it last changed???

 

[goomer416]

X3 spent over 500$ replaceing shit till we finally said wtf.. fuel filter!

 

[bootlegcivic]

fuel filter replaced 2 months ago.. but there is a slight fuel smell in the car as it idles and it idles fine

^^ what the hell did you spend $500 on replacing?

The only time a car has ran like shit besides boncing idle, was loose plugs/wires, retarded timing, and no compression (well a lot less then the others).

what have you done to the car recently? Put shitty gas in? Last time you had a tune up? Need more info, a random my car runs like shit is worthless.

tune up done 2 months ago with filter change nothng done to car recently

i'll throw out 'vacuum leak'.... kinda doubtful, but take a look under the hood and make sure everyhting looks OK. Check the plug wires (my car runs great when a plug wire falls of the dizzy cap, lol), and pull the plugs.... good luck!

went out and listened to it this morning and there is a loud hissing sound fron the engine near the firewall on the drivers side??? vacuum leak? any clue as too which hose?????

 

[fade2blk500]

My car did this same thing, I had a big vaccum leak off a 1/4 inch rubber hose that went into a t-fitting. right on the left side of the intake. Check out all those hoses and make sure they have connections.

 

[fade2blk500]

btw it was on the back side of the intake mani. like near the firewall.

A full tune up, injectors, and then them hookinh it up to the diagnostic machine... only one in town so then can charge w/e they want... then labour! thats 500$ cnd too

ok another cule to the mystery when the car is cold runs fine but if it idels for longer than 10 min it starts to bog down......update refilled tank today hasnt boged since bad batch of gas????? I knew $1.99 a gallon was to good to be true will keep you gus updated.

If it starts to idle poorly after engaging closed loop then maybe the primary oxygen sensor has gone bad.

 

[bootlegcivic]

when u say primary ???? i have only one oxygen sensor so could that be the problem is there a way to test for this cause those things can be pretty pricey.

 

[bootlegcivic]

wtf i cant edit my last post so i had to make a new one .... the car idles fine its when you gas or accelerate it bogs down hope this clears it up and thanks for the suggestions so far guys

if the new gas doesnt fix it, you might oil getting to your spark plugs.

your clues point to this problem. its easy to check, so let me know if this is the problem.

 

[bootlegcivic]

ok guys must have been a bad bach of gas cause after i ran it down to almost empty of the $1.99 crap i refilled at $2.29 a gallon and now it runs fine thanks for all of the help.
