Eating gas
not quite an alero but my room mates sunfire has the same 2.4 5sp that came in the aleros. We've only had for a week so far, just replace the intake air temp sensor and the cams/ cam sensors/plugs, pretty much a full tuneup was done before we got it. We thought the intake air sensor was going to be the last of it but he just took it on the road and it threw a code again as well only getting 14-16 mpgs on the highway. Assuming its the same code as before its a misfire on banks 1 and 2. Im thinking the next place to start is the upstream 02 sensor. what else?!
also Only two times in the week we've had it so far its ticked upon start up, im pretty sure its the timing chain tension problem as is common with this motor. shurly that wouldnt through it off THAT much though right?
I dont know this twin cam like i did my old ecotec, any help is appreciated, we need to get the last few kinks worked out. Thanks in advance.
