Please help! Surging issue!!!
I'm new to the forum but I have been reading on here for the last week trying to figure out what is wrong with my car. I have an 07 GT Convertible and my alternator went out Thursday of last week. I had the diodes and brushings replaced. My car idled smooth for 5 seconds and surged for 3, etc. Today, I decided to change my fuel filter since it hasn't been changed since I purchased the car (yes, I know. It should be changed every year.). Once I started my car it still surged. I've read basically every single thread on the forum pertaining to surging. I'm at my wit's end and my pocket book is looking very skinny. Thanks!!!!!!

Go to the parts store and buy a7 dollar can of throttle body cleaner. Over time you get a build up on the throttle body that restricts air flow while idling, the computer automatically adjusts for this as it's happening. When you changed your alternator you reset the computer and erased the data it was using to run smooth with the build up. give the throttle body a good cleaning and it'll purr like a kitten

THIS!
I had the same issue, but it also died on me at the light. And even got the car in LIMP mode. My throttlebody was gone though, according to the dealership. Next time however... I shall clean my TB!

I cleaned my TB. Still surging. When the car surges, the lights dim, rpms go down, and you can hear the fuel pump. When I took the TB off, the butterflies weren't sitting flush. They were actually at an angle. Is this how they supposed to be? This is the first time I ever had to work on my car and not sure how the butterflies are supposed to fit.

After you cleaned the TB and MAF sensor did you disconnect the battery for 15 minutes so that it could reset again?

you can get bad new parts. it happens. take the alternator out and battery and take it to a parts store and get both tested to see if they are working fine. that will be the cheapest way to cut the two out if it is not one of them. i know o'reilly's checks both. good luck. hope you get it fixed
