Cashville Posted December 6, 2011 Report Share Posted December 6, 2011 Hi. I've been having a problem with my Hummer H2, when my car is in D or R, the RPM needle jumps a little bit, and the car also vibrates a little and I noticed a loss of power in the exhaust. By turning the lights on, I also noticed they sometimes flicker, like losing power. I've also noted on the highway, that sometimes it looks like the car looses some power just for a millisecond, and keeps happening. I though it might be the battery, because it happened to me on the highway yesterday for example, so as soon as I got home I put the battery charging. Today with the battery fully charged, I used the car for like 5 miles, and when I was waiting for someone with the car in park I noticed the exhaust sound kept changing its noise, like it was loosing power for a millisecond also. I then put it on park and noticed the rpm needle was jumping, so I made a little video: http://www.youtube.com/watch?v=QxuSsdd6Qgk I'm shiffting from D, N, R to P in the video, you can hear me do it, and the needle only jumps on D and R. Because I'm thinking this might be a battery problem, I'm going to post pics of my stereo system, so you can have an idea: This is all being run only on this battery: I bought the car like this almost 3 years ago, I think this battery might not be sufficient for everything the car has, and maybe it's dying and the symptoms I'm getting are from it. I don't know for sure that's why I'm asking, because noticing loss of power in the car, and I mean wheel power on a highway (and it's really just for a millisecond, like little stumbles every 3 or 4 seconds) might be a symptom that excludes it being a battery problem, I don't know... Any help would be appreciated. Regards Link to comment Share on other sites More sharing options...

D-train-13k Posted December 7, 2011 Report Share Posted December 7, 2011 Dead cells in your battery? That won't show up as bad voltage. Recommend doing a load test on it.

TeamHT Posted December 7, 2011 Report Share Posted December 7, 2011 You again? I remember something electrical being your issue or concern maybe a year or two ago... I am thinking maybe your issue is not electrical. Check your intake assembly? Maybe a new throttle body gasket or something wrong with your MAF sensor. Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...

Yeah, I took the onstar fuse oute, and the quick battery discharge problems stopped. I guess I'll try the injector cleaner to see if it makes any difference Link to comment Share on other sites More sharing options...

Cashville Posted December 7, 2011 Author Report Share Posted December 7, 2011 last time it had a proper tune up? i know its a stupid question but you wont believe some of the stuff i see..... About 6 months ago. It was in a garage because half of the engine stopped working. It was an oil passage way that was clogged. They cleaned it, put everything back together. They changed the oils and filters, and also changed the spark plugs while it was there. About a month after that I put a new air intake, Airdoc. The car has been doing this for some time, I can't remember exactly, but I think it was previous to me putting on the new intake. Link to comment Share on other sites More sharing options...
