Its been years since I’ve posted on here, and I miss it. I hope everyone is well, I know there’s less activity now than there was in 2012-2014 when I was on every day, but believe it, the 1993 pearl green Q45 is still mine.
-I bought that car from a guy in washington in 2012 and had it shipped all the way to me in Massachusetts. It had a misfire, api had some work done and changed the injectors, fuel rails and wiring harness to ones out of a 1994, and that fixed 95% of the misfire issues. I am the second owner, the original owner was a retired lawyer who had a law office 5 minutes from home, thus it had 60k miles.
-I moved to Florida in early 2014 and of my three cars, this was the only one i had flat-bedded for the trip, even my SC400 was driven.
-I continued to love it, but in 2016 while browsing autotrader, a 2005 Q45 with 59k miles caught my eye. The following morning I hauled AZZ to the dealer in Pompano Beach, and it was gorgeous, and mint throughout. I plopped down $11 grand just as an email came in with an offer of $13, but the title was already mine. This is the best car I have ever owned, whether price is a factor or not.
-I considered selling my beloved 93 on craigslist, but a few days later decided to be a good son, and put it on a flatbed to my mom so she could have it, and I could have a car for the few times a year I come home to visit.
-This is where the story takes a different turn, my parents are not what we can describe as up and coming, upwardly mobile, or driven individuals, with nearly everything from cars, houses, appliances, etc, when things break, they remain broken. Cars for example have never been washed because why bother if it rains, or vacuumed out for years. The sunroof no longer works because they simply hadnt used it for years, and each time i visited the motor would get weaker and weaker. The misfire has returned and granted my dad finally gets the point of using techron to help it, but at idle its still very bad.
-I realize ive put a 30 year old enthusiast car into the hands of two people that simply don't understand the importance of maintenance (or care), but as all things are with them, it wont get done unless I do it, and as such next week it will be worked on by a professional shop a few towns over from them. I am providing them with a set of 8 injectors for the 94, rebuilt and 8 factory recommended spark plugs, for the minimum to solve the misfire. I am certain there will be so much more but at least the engine will run smoothly and the wheels aligned.
….. wish me luck, boys! He only has 107,000 miles on and has 107,000 more to go!

I'm still NOT well ..............and I was born in MA

Beautiful SET o' wheels ,yes , nice jestures too my MA friend (me Boston City)

You’re likely before my time here but, I feel ya 100%!! My parents are the same. They don’t fix s*** when it comes to cars. Seems like they used to, but I think they just got burned out on the used car rabbit hole. I’d always watch them trade in cars that woulda been great if they had the money to put into it. My favorite was a 88 Lincoln Continental that reminds me of the q45 (funny how they brought them back) and a Volvo station wagon. They were just too high maintenance and got traded out. They now have a low mileage, mid-teens Sentra that looks like a nimble Infiniti.

I just had to buy and pay labor for brakes on my Maxima because my mom just doesn’t do s*** about repairs unless it’s a “breakdown”. Meanwhile the rear pads were down to metal, throwing rust particles as far as the bumper paint, smh.

Only suggestions: be sure the missing isn’t coming from a leaking valve cover getting on the coils. If so, it could be as easy as running some stop leak after an oil change. I know that was one of my first problems with mine: 2 spark cylinders were flooded with oil. I couldn’t do the job right away, but after an oil change and some stop leak: it cured it and stayed dry until I was able to replace the gasket a couple months later.

Got one for ya 98_Q45..........................Boston mentality.............got a SZHITT-BOX on the side
Back in the day even a Mercedes parked wrong and a Boston cop would say " GET THAT SZHITT-BOX ATTA HEEA "

wicked Smaaat , huh..ya...huh...ya......huh? ? ?...............OR......A wicked pissa ........ya

Alright, its going in tomorrow morning. My parents are bringing it in with a set of 8 rebuilt oem fuel injectors, two brand new knock sensors, and 8 new factory spark plugs.

-Im hoping they figure it all out by midweek so we have an idea of what needs to be done, get the job worked, align wheels and get it back to my parents.

Make sure to tell them to be careful with hoses under the plenum, when swapping out he injectors. Some can be replaced with generic sold by the feet hoses, while others can't. Having a good set of hose pliers helps. Also, the IACV gasket is hard to source, and may need fabricating or re-use. Also, premium fuel is must for the car, and the car will knock on regular.

Absolutely.

They quoted me a monstrous amount for the work to be done, so I called up the original shop also local to my parents and they were able to quote roughly half the cost. They originally were inside of it in 2012 when i got it, and even pulled up the invoice from then… replaced all injectors, rails, harness, knock sensors, spark plugs, coolant flush, oil change, drain and refill differential- the entire job was $1,100. Their labor rate is up from 59 to 89, but the injectors and knock sensors should be reasonable enough. I had to buy a set of 8 intake gaskets, im trying to supply everything needed to make it easier for them.

I always ran (and my dad always) 93 octane fuel, no exception.

You said '94 injectors - I'm 99% certain that they're a different style than the 90-93. You'd need different fuel rails and a different injector sub-harness to make that work.

To OP (or Charlie, or anyone else):
I have a small number of new in package gen-u-ine nissan IACV (aka AAC) valve gaskets. $6 shipped first class to USA
AAC GASKET- INF#23785-60U01
Regardless if you buy a new one, or manage to re-use I have had good experience with a judicious (read....small) smear of red axle grease to keep those gaskets from sticking and allowing a few times of re-use (until they are overcompressed and no longer seal)

good luck, and hope the '93 is running sweet again soon.
PS-you have verified the chain guides?

His original post notes that he updated the injectors, rails, and harness to the '94 style.

I've used RTV instead of a gasket the last couple times I've had it off, with no apparent leakage.

Looks like I missed that.

Yes i have. Verified they started using metal chain guides in 11/92, and mine was built in 01/93.

Those are some sweet rides!
Glad to see people taking care of them!
