It turned out the starting issue was a dirty/faulty TDC sensor - a common fault on this motor. A quick clean and it was like brand new - until a coil pack went. Replaced all the coil packs, and plugs while I was at it (still had the original Denso ones from 2000 in it), with decent OEM Valeo ones and Bosch plugs and it went back to running ok-ish.
The engine had always been a bit rickity, as if there was a missfire, and always a stench of fuel. Mileage was only at 26mpg - rediculous. So began to suspect a bad injector - stuck open - as I couldn't find anything suspect on OBD readouts. Thinking that since this car had sat for 13 years doing nothing, it's probably gunk in the injectors or injector rail.
This is where this comes in (Finally). I was very suspect this would do anything - it's only an additive afterall, so I threw a full bottle in a half tank of fuel (it's a ~10 gallon tank). Well, it's been a few weeks, and I went through a second bottle too (may as well as I got it elsewhere for a good price), and I'm now getting 40mpg. What a difference. The car no longer idles badly, it starts perfectly fine (previously it would seriously judder after a start), and I'm getting far better reponse from it.
It's saved an awful time consuming and costly fix, so I can't praise this stuff enough. In the last year of me having the car, It's been a job sitting in the back of a long queue of DIY jobs that I was dreading to get to.
I doubt it would do much for a perfectly fine running engine - but if it's not, and you suspect the fuel delivery system, this may just do the trick for a fraction of the price and effort.
I'm more than happy - a $100 car, with two previous owners, with only 24,000 miles on the clock and a body in mint condition. Can't be happier than that - especially since this stuff brought it back to life and running like brand new!
Now, just to get the Air-Con working (I suspect the expansion valve for much the same reason - gunk!).
Glad it is on subscribe and save.
I kept the Amazon shipping box with this product inside in my car, so I can add this product when I refill my gas tank after the current tank runs out.
Following this action, I have been smelling heavy oily odor in my car. However, I didn't realize any issue with the package but thought it was caused by gas or oil leakage of my car. I experienced dizziness and light headache for several days but could not find where the problem was until I went to a gas station and opened the package. One of the two bottles was half empty and covered with grease. The strong odor coming out it was fainting. I discarded the bottle immediately.
Don't make the mistake that I made. Be aware of the risk of a leaking package and don't keep it in your car without careful inspection.
