Hi all got a 3.5 efi that was running fine till it met very deep water,now it ticks over fine but when you rev it it sounds to be running on 7 and is well short of power,have changed the plugs/leads/arm and dizzy cap.Any ideas would be welcome.Cheers Pete

Skibum346:
Couple of questions...

Do you have a snorkel?
Is it properly sealed?
Did the ECU get wet?

If you have no snorkel, or you do but it leaks (what's the ***** point of having it then?!) there is a chance you've sucked water up and hydrolocked the engine. That said I wouldn't have expected it to be just one cylinder.

If the ECU got wet it may not be performing as it should, but again, I would have expected that to affect the whole engine rather than a single cylinder.

Now that the bad news is out of the way, make sure none of your HT leads are shorting against anything... and if you haven't changed them in a while... get a GOOD set.

Good luck.

Snorkel good and sealed and have moved the ecu so that stayed dry.Had to bring it home on a trailer,lots of wd40  and  left the dizzy cap off for a day or 2  to get it started but won't run right.Pete

jjsaul:
if you havent replaced the dizzy cap after you drowned it, it may have small cracks in it

am thinking what else it could be....mine did that a few times then seemed to cure itself...and i dont have a snorkel or have moved the ecu  :roll:
