KY FD owner since 1994.

I've owned my 1993 FD since 1994. Not new to this site, but have never posted on any forums. Looking forward to gaining some insight into some of the problems I'm now encountering with my 25 year old.

Nice. I'm assuming completely stock and serviced by dealer? I purchased my 93 from the original owner and the dealer had led her astray many times on the issues the car was having. What problems are you experiencing with the car?

Thanks for the quick response. I had my engine rebuilt about 10 years ago at 103,000 miles and the gentleman who did the work did an excellent job. However, in the past year I've been experiencing some issues with start up. If the car sits for a few days, it will start immediately, however it runs very rough for about 5 minutes or until it's warmed up. After it levels out, when I start out on a trip it will hesitate and sometimes backfire at 2000 rpm's. Always at the same reading. Again, after a few minutes this stops occurring and it runs fine.
If I drive the car and then shut it down for a period of an hour or so, it has a hard time starting. Seems like it's flooded. If I floor the accelerator, it will then start after a few tries.
I've had my mechanic check the compression and it's at 125 to 130. Also checked for vacuum leaks, etc. and can't find any problem. So we're kind of stuck where we are.

I've been thinking it may be a bad fuel injector that is leaking internally, but that's just a guess. Hate to spend the money replacing them and not resolving the problem.

So, at this point I'm just looking for any opinions on what the problem may be.

Thanks,

Al Lerch

Sounds like a sticking injector to me. How do your spark plugs look? If dark and wet, you’ve either got too much fuel or coolant leaking into your combustion chamber,

Thanks for your input. We did changed the plugs, the old ones were dark, not too wet. Checked and no coolant in the combustion chamber. Do you think a good cleaning of the injectors before replacing would be prudent?

Thanks

Second leaky injectors, or a clogged air filter. It's good to have your injectors serviced if they are orginal.

Another culprit may be your O2 sensor

It may be worth running a bottle of injector cleaner through your fuel system. I use Redline Injector cleaner once each year. A half bottle per tank through two consecutive tanks ‘could’ clear it up. It’s worked for me before and is worth a shot.
