Could be a couple things. I would start with the heap stuff. Clean all contacts and rotor on he distributor cap. Also pull all your plugs and make sure they have strong spark and are free of debris. Then if you still have the problem with the 52 code try replacing your O2 sensor it may be throwing your ECM for a loop while its running.
