ryjaytay38 Posted December 10, 2016 Share Posted December 10, 2016 Can anyone tell me what I'm looking at? My 2001 Pathy was always starting immediately, but I thought with 215000 on it, a bottle of injector cleaner won't hurt. I added it and now it has trouble starting. Once it's running down the road, no problems, no hesitation, no stalling at stop lights. But to get it to start can be a challenge. I thought maybe a fouled plug or injector coils? If anyone can shed a little light on this issue and let me know what I might want to try, it would be greatly appreciated! Link to comment Share on other sites More sharing options...
LittleFR Posted December 10, 2016 Share Posted December 10, 2016 Injector cleaner doesn't just clean injectors. If I was a betting man I would say you had years of filth and gunk inside the tank and it broke it loose. My bet is fuel filter. Link to comment Share on other sites More sharing options...
ryjaytay38 Posted December 10, 2016 Author Share Posted December 10, 2016 Wouldn't it affect performance when I'm driving too? Link to comment Share on other sites More sharing options...
Slartibartfast Posted December 10, 2016 Share Posted December 10, 2016 (edited) Yep. A bad fuel filter should show up most when you're using the most fuel--so it would have issues when you get on the power. How much fuel was in the tank, and how much injector stuff did you add?

ChemExposure Posted December 11, 2016 Share Posted December 11, 2016 Well damn, I just came here to ask what "additives" R50 owners have succesfully used. Definitely not going to use fuel injector cleaner now. Link to comment Share on other sites More sharing options...
ABCAB Posted December 11, 2016 Share Posted December 11, 2016 You could also have dislodged a resin build up in the pipes between the filter and the injectors. Now that gunk has broken loose and stuck in your injectors. Spray pattern is compromised and no good for cold starting, but not affecting higher revs performance that much, with enough air swirl to achieve combustion conditions close to normal.

RCWD21 Posted December 11, 2016 Share Posted December 11, 2016 Well damn, I just came here to ask what "additives" R50 owners have succesfully used. Definitely not going to use fuel injector cleaner now.It isn't an issue of fuel system treatments that are bad it's just a fuel system needs to be kept taken care of from the start to avoid issues when the fuel system cleaners are used, if the OP bought the vehicle used then there's no telling what the previous owner(s) did or didn't do. And generally as long as a vehicle hasn't sat for long periods of time the fuel filter will catch most of what gets broken free or dissolved in the fuel system, That's why they're there and probably what's causing the OP's problmes. It could also be injectors that are failing electronically and they just so happen to fail when the cleaner was used.

LittleFR Posted December 12, 2016 Share Posted December 12, 2016 I use Star Tron exclusively. But I have used Lucas in the past with no issues... But both have made me change a fuel filter. Link to comment Share on other sites More sharing options...
rgallant Posted December 12, 2016 Share Posted December 12, 2016 I always change the fuel filter a couple days after using injector cleaner - I figure if I need to run that my filter should be changed out. Link to comment Share on other sites More sharing options...
