Well my check engine light has been on for a while and I am wondering where to start. Here�s the info.
Check engine lights been on for a while. The cars stalls some times when started, its starts up and reaches about 1500-2000 rpms and then drop to 0, will do this 2-3 times in a row on occasion. Happens randomly sometimes not for a week or so, maybe more frequently in the cold?.
Stalling during left turns usually braking into left turns, even with close to full tank of gas.
Hesitation at low rpms, happens occasionally usually while engine is cold.
Went to AutoZone today and that the check engine light check/scanned. Here are the results
P0133-Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 1.
P0153-Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 2.
P0401-Insufficient EGR Flow.
P1151-Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2.
Where do I start, the car probably need some scheduled maintenance. Here�s my list.
Spark plugs
Fuel filter
So what�s next, from what I have read, and I have read a lot on these forums already 8 hours worth I would say.
IAC
PCV
EGR
EGR-cleaning
Vacuum leak
Intake (upper/lower) systems rebuild
Fuel filter
Fuel pump
MAF
Spark plugs
So please give me some input and where to start!!!
