find a shop or someone who can pull obd1 codes from your honda...should be straightforward
Aren't you amazed when the actual person that asked the question replies? Can they 'pull the codes' in reverse? Is chocolate pudding a good source of fiber?
Yes, codes may be pulled in drive, neutral, park and even reverse... Chocolate pudding itself is not a good source of fiber.
Have you pulled the codes? If not, do that and repost please.
