i have the same set up 97 with 2.5L i find my jeep starts and runs way better when its cooler out but that just hast to do with more air
but to deal with high heat low speeds i am putting electric cooling fan as well as cold air intake
i have been told this will help with the low speed city driving and low, rough idle
hope it helps but is sounds like the other know better what they are talking about
lol
