I did unbolt right side of rail to bolt on a cold air system but didn't pull it away, could this be causing the lean issue cause as I said I didn't pull out on injector causing it to race rpms?
And just so your aware put stock air box back on to try and eliminate issue and the same high rpms. And there are no codes now just lean bank 1 and high rpms. Used starting fluid to look for leaks and nothing, same problem occurring 1500 to 3k rpms, leaning more towards bad throttle body.

 

[QUOTE=HHR guru;477553]Was wondering if I could help anyone. Questions are welcome and discussed in detail.
I have a 06 hhr and when I turn the key the starter doesn’t engage the flywheel I have put a new starter on….could this be a bad flywheel problem? Or am I missing something?

 

Hello, I have a 2006 HHR with 220K miles, it has been extremely reliable, recently my MPGs had dropped some and I had a slight rough idle so i changed my air filter because it was due and I changed my spark plugs because I couldn't remember when they were replaced last and figured that was the cause of my issues. With the repairs done I started the car and it idled perfect but always idled well when cold so I drove around about 4 miles everything was perfect. Later that night I drove about 5 miles and was on the interstate and floored it to make a pass as usual it down shifted and took off, pass made I resumed normal speed and felt a little hesitation, I took the next exit and when I let off the throttle the car started to buck and the CEL came on, stopped at the stop light the idle was all over the place and the car shuttered, the TC light came on, and as I pulled away the reduced power light came on. I pulled over and checked codes P0068, 0101, 0106, 0300, I cleared the codes restarted the car and headed back home, about a mile later it happened again, cleared the codes ad restarted the car, it ran a little rough and felt unresponsive then all of a sudden it took off and ran perfect. About 2 miles later I stopped at a stoplight and the idle was perfect, a mile later CEL and power reduced back on, reset and made it home. Google search suggested cleaning the TB, this made since to me with the high miles, cleaned TB with carb cleaner and moved the butterfly with my hand, restarted idled was rough for a minute then smoothed out, put it in reverse and i felt the RPMs go a little high, driving the RPMs stayed around 1500, drove about 4 miles and CEL back on, got home and put it in park and the idle went to 3250, CEL code was P0121. Thinking the TB was the HHR weak point and it has 220K on it I replaced the TB. Now in park it idles at 3250 RPM and in drive it will come down to about 1250 and is smooth, with my foot off thr pedal it cruises about 35 MPH and will surge sometimes. I drove around today for 2 hours stop and go on a road with a 45 MPH limit stopping about every 20 minutes shutting down and restarting. No change, with the car off and the ignition on my OBD reader shows the TPS fluctuating between 23% and 34% one or the other up and down, with the car running it holds 34% in park. Any help would be appreciated, retired and would like to stay out of the dealership if possible

 

bought an '10 from my brother last week, and might have an inquiry now & again.

 

I was driving around doing errands and my car just shut down. No crank/no start. When I turn the key I can hear the fuel pump humming and the relay clicking but nothing else. I already checked fuses and relays and the starter has spark. Also replaced the battery. Any help would be greatly appreciated.

 

I removed the plastic covers around the column and ignition and found if I push the white plastic that has a spring on it. It will release the key from the ignition. Now I have no power at all when I try to turn the car on with the key. No lights, no door chime, no power whatsoever when key is inserted and turned on. Nothing happens when turning the key to start/run. I can turn on headlights manually and they seem bright. Battery voltage reads 13.45 volts. I can't even get the car to go into neutral so I can push it out of the middle of my driveway. Also the steering wheel doesn't lock at all.

 

last night my car did not start up at all.But have not had any problems with it.Recently, at all with it starting.But what i'm worried about is hiring a mobile mechanic just for him to come out and give me some broad answer on the problem.I was wondering, should a good mechanic.Be able to pinpoint at least why it won't start?
battery and starter are good and I know that the serpentine belt is turning when I'm trying to start it.
