Is it true that the 94 VE30DE got it's VTC problem fixed??

 

No, I have a 94 SE and my VTC's went bad.

 

Well that was easy.

 

hi i have a 92 maxima se and was wondering what a VCT is because my car has een messing up ocasionaly its hard to explain what it does but it hesitates or jolts when excelerating and i was wondering if anywon else has this problem it also has mood swings one day it will smoke mustanges other days il loose to cavaliers and was wondering what might make my car be fast one day and slow others any replys are greatly appreciated thanks

 

The VE30DE had variable valve timing, the VTC (valve timing control I think) is the mechanism that varies the valve timing. When they go bad, it's $$$. If it isn't that, then it sounds like your AAC valve, it controls your idle and allows more air into the engine to make power as compensation for when you turn (use power steering), brake, etc. When these go out, your car will buck violently, miss, stall, die, refuse to start and have a generally erratic idle. They aren't hard to replace. I haven't done it on a Nissan, but I've done it on other vehicles.

 

about how much is an AAC valve and where is it located on my car also some one told me it could be my fuel injectors but it almost seems like it would be my fuel pump because when it messes up it seems like it looses fuel for a second or just a split second but if the AAC valve is reletively inexpensive and not to dificult to put in its worth a try thank you so much for your responce

 

I've never replaced a Nissan AAC, but when I replaced the one on my dad's Chevy truck (Chevy calls them Idle Air Controllers), it was $48.95 at NAPA and located on the throttle body under the air cleaner (airbox). A search should turn up something as to it's location. The Chevrolet IAC was a cylindrical, electric, stepper-motor with four wires on it and the end was threaded into the throttle-body. Had to use a 1 inch wrench to get it out.

 

Well... what exactly is the part that goes bad. I'm thinking of modding the he|| out of a VE and i was going to get all custom internals and i was curious what part it was that screwed up.

 

what "custom" internals are you talking about?

 

VTCs aren't usually associated with drivability problems (bucking, hesitation, etc etc.) They mainly just make that annoying clacking noise.

 

pistons, rings, rods, valves, cams, etc...

 

The AAC can cause the bucking, etc... but it won't cause the car to be slow with no power. Personally I would just start with a normal tune up and see what does for him. Also I think I would take a peak at the coils as well and make sure he isn't having problems with one that is missing @ high RPMS or anything...

Just my $0.02,

My '92 SE 5SPD Does the same dam thing, on occassion. It's really annoying!
