Hello guys, here is my problem. On my 93 saturn sl1 1.9L it has 206000 miles on it. I have replaced the fuel injector, cts, plugs. Wires are in ok condition and getting good spark at all cylinders! Just changed oil and filter. So my problem is after changing all the named parts I still have an issue with the car flooding it self out. After replacing everything noted above I let the car idle and warm up for about 20 minutes. Idled great and reved nicely. After that I went to take it for a test drive! I made it about 3 blocks and it just died! Seem as if it does this when the clutch pedal is pressed down! Also the check engine light is off after changing out injector, plugs and the cts. Any help with this issue would be greatlty appreciated! !

Are the plugs wet with gas when it dies to confirm flooding? If so, have you checked fuel pump pressure to make sure the regulator is working properly?

Since you replaced the CTS, it sounds like either there is a stuck injector or the fuel pressure is too high. Have you checked pressure?

I have not checked fuel pressure, I also just replaced the injctor with a new one. Would a bad fuel pressure regulator also cause to high of fuel pressure which would override the spring and seat within the fuel injector! Also I veen checking for fuel pressure regulators for my car and the only thing that comes up is to replace the diaphragm within the pressure regulator body that is attached and part of the throttle body itsself! 3

The regulator should be on the fuel rail. See attached pic.

Ok guys here is my last ditch effort to fix this car; I have replaced sparkplugs, fuel injector, fuel regulator, fuel filter, plug wires, new catalytic converter and checked the fuel pressure which is at 53psi at idle.

Once again my problem is that the engine floods its self out! Once it sits long enough fpr the plugs to dry out or I change the plugs it idles nicely then it bogs at about 3000+rpm and floods its self out. Any help would be great!

Thanks

Hello guys, this will be my last ditch effort to fix my car. I have replaced the following sparkplugs, cts., Fuel injector, fuel regulator diaphragm, fuel filter pkug wires new cat and changed the oil and filter!

I still have a flooding issue and now it bogs at 3000+rpm. Everything ran great before the cat was changed. When the new plugs are installed or I clean thebold ones it idles nicely for about 15 minutes then when you give it gas it bogs at 3000+ rpm loads back up and floods its self out! Any help pn thisbissue would be great!

Thanks for all the help!

Have you gotten any trouble codes? Have you checked ignition timing? Are there any codes related to the cam sensor? Have you checked engine compression? I only say that because of the number of miles on it.
