UPDATE: I have the HHR up and running after replacing the Cams that was wrong from Odessa Heads and checking the timing for the 5th time I tore this engine apart and back together I checked the compression and I had 190,200,190,200 great compression. I turned the Key and it fired right up and ran like a Kitten.again I Thank all of you for your input and support and not giving up on me.

 

Is there a way to identify the cams? We have another member having something like the same problem.

 

The way to tell is lay your cams down with the key Cut out at 12:00 and the back end of the cams should look like this picture Note: The Top Cam you see is the Intake Cam and the Bottom being the Exhaust This on a 2.2 VVT engine

 

Awesome news, thank you for the update! And verifying how to identify the cams shafts

 

OK guys I said I would be Back lol ok HHR was running now it won't idle right . I replaced the ACdelco pugs with NGK plugs HHR idles real rough until I press the gas and bring it up to about 1500-1800 rpms then it idles out like a kitten ? any suggestions?I have no codes present

 

Get rid of the NGK plugs. Recheck the MAF connector.

 

Hi Don Miss me ???lol hey what type plug would you use and is .40 the correct gap

 

2.0L L4 Engine M........Automatic Manual.................0.035in (0.90mm)
2.2L L4 Engine B.........Automatic Manual................0.040in (1.01mm)
2.4L L4 Engine V.........Automatic Manual.................0.040in (1.01mm)

AC Delco Iridiums. Some of the other brands have been proven not to work well in the Ecotec family of engines.

 

AC Delco 41-103 Iridium, plugs they come pregapped, don’t mess with them the centre electrode whisker break off if you try to gap them.

 

Thanks
