07 Tahoe hesitates and randomly stalls

[David1221]

Hey guys I have a 2007 Tahoe 5.3 with 113K. Lately it has been a little hesitant if you push the gas hard. Also, it will randomly lose power but if you turn it off and start it back up it is fine. At one point I had a check engine light for the TPS. I cleaned the throttle body and it went away, but I am wondering if it could still be bad. Could the MAF sensor be dirty? Maybe a fuel filter? Any help is greatly appreciated.

You are in the right direction, check the air filter and if you clean the MAF and fixes it then replace the MAF. Cleaning the MAF is only a temporary fix. Also you should monitor your fuel trims to make sure the truck isn't running lean to cause your issue.

Great thanks. I already bought a new filter and I grabbed some CRC MAF sensor cleaner as well. I was going to replace the spark plugs but I was told I already havethe Irisium plugs and they are supposed to be good for 150K. Is that right? 150K seems like a long time to go without changing them out.

Are you getting a reduced engine power on dic ?
