i bought this van about 3 months ago, and it just stated to act like it was running out of fuel, or overheating since our recent heat wave here in the mojave desert. i have replace the fan and switch, and the fuel fiter. it hesitats, spits and sputters, at all ponits of acceletion. it is minimal as long as i accelerate very slowly. i fear that it may be a head or vavle issue, i intend of tesing the compression in the next few days. any suggestions would be greatly appreciated. many thanks in advance!

Good luck trying to kill a 3.3 . I would be looking at fuel pump presure.

dirty throttle body, clogged fuel injectors, vacuum leak in a rubber hose, shorted internally ignition coil pack.
