I have a 2002 Lexus GS300. I put the car turbo with no issues. I was cleaning the MAF sensor I stepped on it and broke it. I bought one off eBay and I put it on the and the car it started doing weird things.it goes pass 3rpm but starts to have misfires and smells like gas it turns on but I have to keep my foot on the gas. I think the computer isn’t reading the new sensor. I put the old broken one on the car and it starts fine does everything fine but doesn’t go past 3rpm. What could be the problem?
