- Timing belt (bought from Bernie B) - New Timing belt tensioner - New gmb pulleys - All new drive belts - Coolant temp sensor - New - Tried a stock ecu I had on the shelf to see if there was an internal ecu issue. - New PCV's - Silicone IAC to PCV hose set - Z1 hard pipes replaced my silicone pipes
These are the parts I've replaced specifically trying to eliminate this issue or done out of necessity for other issues.
