This is a switch located in the shifter mechanism that keeps the engine from starting if the transmission isn't in park or neutral. Just bought a 2003 TB LS used and does the same thing On PARK I've tried to rev a bit but wont go over 2500 RPM, please confirm me that this is a normal behavior of TB 2003 I6 4. But it was also the first time in a while that Engine is running weird like it has a 2500 rpm rev limit. I went out and it was hard reving over 3000 rpm (4EAT) + I can't really hear the turbo spooling anymore. I went to leave the house this morning and it didn't want to start. I put VAG-COM on the car to see what codes it had if any. I have problem with my 2008 honda accord, it wont pass 3000 rpm the problem is I cannot exceed 3000rpm, while speeding it would jerk at 3000rpm and will not make the car exceed that mark. RE: Engine misses over 2,500 RPM IP: Logged Message: Is this how the truck would behave in limp mode? I thought limp mode would limit you to second gear. Dynatrac products are designed using the finest materials, processes and engineering available, and its products are backed by the best service and warranty in the business. When I pull over and park, the engine revs on it's own (not touching the pedal or anything) to almost 2000rpms. 5-05 LLY Forum > 04. Let off on the gas and it goes back to a perfect idle. The leading destination for Volvo owners and enthusiasts. 7L auto that I bought and rebuilt the motor. It now goes, but only until it reaches about 21/2 Rpms. P0642 5 volts refference 1 circuit voltage low Bad ground would give you circuit high,which would be a disconnection, you have more of a bad sensor that is affecting your TPS, depending on the engine this could be your EOP (engine oil pressure) your fuel rail pressure sensor, and other sensor along circuit 1 that causing it to go low. i have misted around the intake with starting fluid with no change as if a vaccum leak would turn up. Thinking its the cooling temperature sensor but not sure. My rpms are going high and my mph take a minute to go higher on my GMC Yukon. IT WILL NOT THROW A CODE!!!!. ok i checked my coolant temp sensor and its fine (seemingly) and my airflow connector+tube and those check out. It is giving p0343 CPS camshaft position sensor voltage high. But, then as I started cruising again my RPMs would not go above 2,000. Engine wont rev above 3000rpm in gear or but will act up again a 5-10 miles down the road nd allows me to ge the rpm up to 5500-6000rpm like it should be doing. All the filters and the all plugs were changed and all was well again.
