BELPRE,
Ohio
My car has an issue that once its up to operating temperature it will start to miss. Ive included 2 logs, one is it acting fine while the cruise is set, and the other it is acting up. It will miss/hesitate accelerating up to cruising speed at first as well. After I logged the bad cruise issue, I pulled into a park and ride as ecmlink kept disconnecting after each log. I pulled out of the park and ride, back onto the highway and pulled from a stop to about 70mph and car pulled flawlessly and performed as it should. I have a log of that as well I'll include just for sake(Pull starts around the 12second mark)
Recent work done/parts replaced:
New built head 1mm oversized valves and springs with hks 264/272 cams(Replaced HG with felpro gasket, timing belt, pulleys, tensioner, and balance shaft belt)
Parts replaced trying to fix the issue;
Fuel pump
Fuel filter
Plugs(NGK BPR6ES gapped to .028) & Wires (NGK)
Front O2 sensor
Coolant temperature sending unit sensor
Logs were recorded with a known working mass air flow sensor
Coil pack
Power transistor(Ignitor)
Throttle body rebuilt and sensors tested good upon rebuilt(Rebuilt by throttlebodies.com)
Stock ECU(black box) replaced with 95 ECMLink(Switched to a 95 thinking maybe the ecu was going bad, it wasn't)
Compression is 165,165,168,165
Mods
3" cat back exhaust(Still on stock dp)
Dejon tool SMIC and hard piping with recirc 1g bov
Known issue
Batt & Brake light illuminate when key is turned on (They are dim, as pulling the ebrake handle causes the brake light to illuminate brighter) they turn off and stay off as soon as the car is started.
Battery is dated 5/19, alt was replaced before purchase(2 years ago, i understand reman alts have a high possibility of a bad voltage regulator)
Gas is a month old.
Any help will be appreciated, I haven't had ecmlink in years so if I should be logging other items to further help, just advise and I will correct my mistakes. Files Cruise ok is good, and Cruise ng is the not good one.
