Bought the car about 90 days ago from someone who rebuilt the top end, full exhaust, new timing belt, new distributor, 'new' junkyard crankshaft pulley. Started off w/ p1336 code, changed out the sensor, line wasn't eaten up but replaced anyways. Cleared codes before inserting new part. Went for test drive, CEL came back on. Checked codes, p1336 again. Drive back to shop, check codes again, now it's p1336 & p1337. Line is tucked and out of the way, YouTube is absolutely no help in this situation at this moment, and I'm at my wits end. This is my only car and I'm supposed to be learning how to work on it but keep running into walls. Any help would be greatly appreciated, anyone else have this issue? I cleared the codes, unplugged the battery, and am gonna run them again.

This is the first code I ended up with.

This came up when I ran the modules.

Got it figured out, we forgot to check continuity on the new crankshaft sensor, we got a faulty sensor out the box. Replaced sensor, codes gone away, no longer going into limp mode. REMEMBER TO CHECK YOUR NEW PARTS !! I also recommend buying the Haynes book for the car, not the Chilton's, if your trying to troubleshoot, test, and replace parts and problems w/ your car.
