Re: 99 intake
havent checked the plugs yet since the swap, (too many other projects) but they were perfect before. hope i dont have to up the map cause then that means i need the map adjuster.

Re: 99 intake
How do I adjust the voltage on the map sensor?
I have a '99 Intake and bored TB ready to install, but have not tackled the job yet. I did install some of the precision Auto 5.0 Bosch fuel injectors. They make it run smoother and helped limit the stalling problem I have for the first few minutes when the engine is cold. It might make more power, but I'm not sure. I was hoping for better fuel mileage, but it seems the same. I have 300k on this engine (1993 4.0L XJ).

Re: 99 intake
it sounds to me that if you 300,000 miles on the jeep and its a stock 4.0 and it stalls after it warms up, its probly due to loss of compression. a stock 4.0 should not need the 24lb injectors, if it does run better with them its because of the extra fuel makeing more compression.
