Engine Trouble Codes

[1999isada]

Got a new computer and cant find the cd for my code reader, my hypertech max performance programmer came up with 2 codes P0138 and P0327. Can someone please help me and tell me what the codes mean?

I know mine had a P0136 which was oxygen sensor related. We need more info on your car(modifications, mileage, service records).

Just looked online:

P0138-downstream O2 sensor high voltage

P0327-Knock sensor fault

i replaced the knock sensors before so i hope its not that. i also replaced 1 o2 sensor and maybe this 1 needs replaced now. i cleared the codes and am going to run some injector cleaner through it. the car sat for a while so im hoping it will be a quick fix. thanks everyone for your help

If you overtightened the knock sensors, then you could be getting a "false knock" where the sensor is so tight, it pics up EVERY vibration in the engine. Try the fuel injector/system cleaner and get back to us with your results.

Use Techron, it costs a little more but it really works. Some of the others are just dry-gas.

Well I put Lucas injector cleaner and fuel treatment in it. I've only put 6Lucas or 7 miles on it but so far so good. Hope that took care of the problem. Thanks for the advice

OK. If anymore issues arise, let us know.

All is good still, think it just needed some fresh gas run threw it. Thanks to everyone
