So I accidentally let the car get rained on. Had it running really well just the day before. Now I am getting surging, erratic rpm behavior and it just barely runs. Tried quite a few things, looking for suggestions or what I can provide you guys to help me. Kind of baffled.

Got it running this evening. Started to adjust the master fuel and it cleaned up and ran very well. I got a little carried away and reved it a few times and noticed some sparks coming out of the exhaust manifolds. Hoping this is just carbon? Quite a ways to go, but its nice to hear it run, and here is to hoping I didnt do any irrevocable damage.

Adam, why would I not be seeing any engine speed change during cranking? I am using the 1uz vvti base maps now, so that should automatically include the tooth count specs and settings for the trigger wheels right? I think the cam trigger is 5-2 and the crank is 36-2. The only thing I am thinking I should have to setup on the trigger side of things is the offset or base timing. Can you confirm?

Thanks for your reply Adam, I switched those settings this evening and got some promising pops from the engine before my battery died. I hate to be the new guy that doesnt have a clue, but I have few precious outside sources of information. My injectors are marked even on the passenger side 2-4-6-8 and odd on the drivers side. I am not exactly sure how the wiring guy correlated this to the outputs, but it wouldnt be difficult to figure out. Edit, my wiring guy sent me this picture: So how would one designate how/when/what group to fire at which point? Im assuming its a relationship with the trigger location and maybe the firing order? I hope the question makes sense and I appreciate your quick response.

I bought a g4 storm new in box from a local distributor in MD over the summer and have been having some issues getting a first start on it. To start with I loaded the 1uz VVTI base maps i found in the file, but was informed those may be the wrong maps to use. Claiming the maps in the file are for a 1uz VVTI 'Extreme'? and wouldnt work for your standard 1uz. Can someone confirm if that is a good place to start? 1995 S chassis 1998 1uz VVTI G4 Storm
