Check for a vacuum leak somewhere. When you have pressure by going faster it will not be a problem but if slow it will cause a problem. TLT

When disconnecting an O2 sensor it could cause damage to the EGR system. Why was it disconnected in the first place?

ENGINE GETTING VAPOR LOCKED.YOUR AIR FILTER COULD BE CLOGGED.

SOURCE: my car keeps burning oil

Smoke from oil being burned is blue,, so I dont think that is the issue.. Black smoke is unburned gas.. The cause of this could be several things - to include he following..
The most efficient thing to do is -
replace the fuel filter(s),,
replace the oxygen sensors,,
replace the air filter,,
replace the pcv valve,,
plugs + wires,,
Check the timing.....
These things are not a furtune and could very well take care of the issue..

I hope this helps !!

Change the belt it sounds like it may be split somewhere.Just remove it and inspect it .

90% of all transmission problems are due to a defective battery. Why? because of the electronics they run off of. Now is it crank no start or no crank condition.
Start off with battery. Make sure its fully charged and terminals are a-ok. Then do starter checks . Let me know what you got at this point ,, cause chances are if battery died the codes are lost . Keep me posted I
'll get you threw it.
