2.2 swap cel no code

[dwitsman]

~~finsihed a 2.2 swap into a 99 obl that had a 2.5 , 2.2 was out of 95 legacy ran great no codes in the 95 , put it into the 99 smoked at first ?? don't know why but quit then threw a cel , BUT no code , reset

drove some more threw CEL again no code, engine also hesitates from a stop

and seems underpowered with heavy accel. did not do that in the 95, had underpowering prob with orig 2.5 but it blew blue smoke after 1000 miles

haven't driven a good running 99 so not sure what feels like normal accel, or going up hillls

any ideas on a cel with no code

and underpower situation ??

You may need to use a better canner on the no code thing. But maybe an o2 sensor? I would get that with Blu when his o2 sensor was failing.

Blue smoke could be from changing plugs and getting oil in there. On a 95 I think the plugs are in the middle of the heads and there are Orings around the plugs. But the last few I did were DOHC's and 97 2.2's so I haven't seen a 95 recently but I do have one on the trailer. Just too lazy to go out in the dark and look at it.

 

Or if the engine was on a stand and you twirled it around someitmes that seems to cause it.

 

CEL with no codes doesn't sound kosher. You need a better reader. My 50 dollar one works well so I wonder what you're using.

 

 

Did you look at how yucky the throttle body was when doing the swap? Did the engine run without hesitation in the 95?

 

You had to redo some small vacuum lines due to the charcoal canister being moved from the front (on the 95) to the rear (on the 99) so perhaps something went wrong there.

 

I forget what goes where but I think you may end up plugging one of the holes in the intake manifold above cylinder #3. I get them mixed up what year engines into what year car body's causes which work arounds.

 

All things to check.

 

Does it still burn blue at the start?

 

If you get a CEL you really should be getting a code and probably pending code(s).
