Well, I told you all about my loss of power over the weeks, still havent got it to a maintenance shop (way too busy right now, plus I am moving for Pete's sake)... Well yesterday, she starts acting up again, felt like she had the hiccups. I was sitting at a red light and the car literally shook every few seconds, as if it had the hiccups. Just rolled over the 111,000 mile mark too... I hope this isn't the beginning of the end...

anyone experience this?

Have you had the exhaust O2 sensor checked?

Dont worry about mileage man your gunna be fine till over 200 if you treat her right..

Anybody have any advice? im thinking its most likely a fuel delivery or throttle problem.. maybe a sensor or something.

this is gonna sound weird. but do you have your air conditioning on? whenever i have my air conditioning on and iam idling at a stop light it will idle rough every 10 sec. or so. Just a thought, but check it out.

My car does something like that, but it is because it downshifts too late. Ia your car auto?

**billycuth** · 06-09-2005, 07:40 AM

thanks guys... yeah it is an auto, and yes the A/C is on. However, the power loss was noticed with out the A/C and it still idles a little too rough without the A/C. I was thinking throttle too, probably needs to be cleaned. And I just had all 4 O2 sensors changed last year, so I sure hope that's not it (those things aren't cheap!)...

Just wondering if there could be anything else I might be missing... Thanks.

You might need to get your ICV (idle control valve) cleaned. What you're describing sounds like it could be that. The good news is to get your ICV cleaned by a shop costs like $20.

**Spieluhr** · 06-09-2005, 04:07 PM

good news^^^

ill have to take care of that and that FI dry cleaning that was mentioned in another thread.

Old worn out sparkplugs will do this, usually the OBC will report 'cyl X misfire' in prologed bad idling, and CEL will turn on for about 2 hours after it stops idling funky. They will especially act up if you get a crappy tank of gas.

Probably ICV. If not that, check O2's, fuel filter\pump, MAF...
(fuel filter should be replaced at least every 100K, really easy to get to but gas leaks out of the hoses when you change it so it's messy)

I'd say blow out and clean the icv. If it worked, great. If not, you are out 20 bucks but now have a clean icv so don't have to worry about that anytime soon. Haha, I had mine cleaned a few months ago.

**billycuth** · 06-13-2005, 07:53 AM

cool guys, thanks. I will let you know what I find out. My appointment is on 6/21...

**komodo** · 06-13-2005, 09:38 AM

Ouch, long wait.

**billycuth** · 06-13-2005, 10:14 AM

I am moving, so I will be off of work. I can't really afford to be without a car for too long. So, I decided to wait till then. I figure if something goes horribly wrong, I will move it up... It hasn't happened again since last week. I know that doesn't mean it fixed itself, but I am also not as concerned.
