93 running rough!

93 3.1L. I've had a CEL on for awhile now showing codes 32 and 43 I don't know if that has anything to do with my problem tho. Recently after some harsh wind and rain (like 100+ mph) I went out to move the car and it started and acted like it was going to die, then after that nearly every time I start it, the car shakes and doesn't really even out too well. I take off and it continues to shake with a noticeable lack of power until it shifts to 2nd, then it seems to really take off. not sure what to check.

Re: 93 running rough!

Check all connections from knock sensor to ECM including grounds. If necessary, have MEMCAL/PROM checked. Which trans does it have?

Re: 93 running rough!

Possibly bad shift accumulator low range on 4t60e trans. Possible bad connection or short in knock sensor cir. Code 43 Knock sen. cir. controls amount of fuel injected by shortening or lengthening the time the injectors open.

Re: 93 running rough!

i'm hoping it's just a knock sensor...although both codes were present before the conditions started. I wonder if the trouble happening right after bad weather is just a coincidence...
