April 7, 20169 yr I've been having a little stumbling usually at idle while sitting at a stoplight. The engine doesn't die but feels close to it. I pulled the codes and got the knock sensor number. I replaced the old cracked knock sensor with a new one from Ebay and it has improved overall performance but it's still stumbling at idle. It's not throwing a check engine light even after putting at least fifty miles on it. MAF sensor you think?
April 7, 20169 yr - Clean the MAF w/the MAF spray - don't use brake cleaner or anything w/too strong a spray. - Clean the IAC - Tune up time? Td

April 8, 20169 yr Author Ran great on the way to the store this morning but when I came out and started it the stumble was back . Turned on the AC and it made it worse. I wonder what I'm missing here? No CEL coming on. Seems like it acts up on every other driving cycle or something? Weird.
