Hey Guys,

Been awhile since I've been on this site. Finally got back into a s13 coupe with a J4 blacktop. I'm running into a few problem and would appropriate it if you guys could help a bit. Everything is bone stock on this car beside a s14 turbo.

How would I know if my ECU is in Limp mode? I ask because my radiator fan (electric) is consistently on. I've replaced the fan relay with another one with no change. I've also notice the car has a infamous RPM bounce when coming to a stop (stock recirculating valve)

The car does seem like it is running a bit rich (can smell fuel) and i'm getting roughly 16mpg.. But the car pulls real hard and doesn't miss a beat.

I'm going to check the CTS and do a boost/vacuum leak sometime this week.

When doing the leak test do I connect my device where the air filter goes and do I block the piping that goes into the intake?
