3SGTE ECU Capacitor Replacement Service. This is NOT to purchase an ECU from Prime, this is a service we offer to replace leaking capacitors on customer's ECU's. The original electrolytic capacitors on these ECU's will eventually leak and cause damage to the circuit board. Leaking caps can cause hard starting, stalling at random, surging idle, super rich fuel mixtures, erroneous engine trouble codes, etc... We can repair some damage to the circuit board, and we know several other common problems that we look for during the cap replacement. Unfortunately, this is not a guaranteed fix for all ECU's. If there are burned/damaged components from a wiring issue or water damage that wouldn't be covered by this service. We have a very high success rate, and we do our best with each one. This is a good idea to do BEFORE problems arise! If you catch the problem early, it is much less likely to have problems that are unrepairable down the road. The longer you wait, the worse it gets. We do not have any stock ECU's for sale, we only do repairs on units sent in by customers.
