Engine Mechanical problem
1991 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic 220000 miles
i have a cutlass ciera 3.3 v6. Starts and runs for about 20 mins then dies. Has spark and fuel pressure is good but it wont start for a few hours. I didnt get any trouble codes using a paper clip. I checked the injector resistances and 4 of them were lower than the book said they were supposed to be but they are still firing. Also when I give it a lot of gas it tries to die unless I let off or it will rev over and over till it dies.
i checked the codes again after I ran it till it wouldnt start. I got a code 22 and a 34. Put a new tp sensor in it and there was no change. Gonna go clean my maf sensor and see what that does.
cleaned maf sensor. No change in running patterns. I get codes 16, 21, 22, and 34. I'm not sure what 16 really means. The book dosent explain it in detail.
took the battery out for the night. Ran awesome in the morning. But after a bit the old attempting to stall and stuff came back. No codes stored anymore though, even after I parked it and it wouldnt start.
