Question about 1999 Saturn SL

2 Answers

1999 SL1 running rough

Car starts, but chugs bad at higher speeds, also rpms are high. We've changed the spark plugs and wires. Could it be the fuel filter? Any suggestions would be great. Sharon

    I have 1999 Saturn SL1, when idling and in "drive" the engine is ruff and appears to want to die. I seems the engine is not getting enough fuel. Also during this time I noticed the LED display on the radio is flicking. The engine idles at 700-800 rpms.

    If put in "park" or "neutral" the engine will idle okay a little ruff and at time the rpms tend to fluctuate from 700-1100 rpms and settles at 700-900 rpms. (a/c is off)

    Car does tend to **** forward as the accelerator is depress. Runs nice once the car is moving.

    The plugs & wires have been changed out about a 1.5 yrs ago. Injectors were cleaned out by mechanic about 4-5 months ago. Air filter is clean.

    Thanks

    Jack

Had a similar problem; started fine but lost power under acceleration and would stall. I changed the fuel sensor relay in the fuse box located on passenger side of interior fuse box. Ran fine after that.

I DONT KNOW FOR SURE BUT I WOULD REPLACE THE M.A.S. AND THE 02 SENSORS. (IF MONEY IS AN ISSUE TRY CLEANING THE M.A.S FIRST)

My 2002 honda civic ex vtec sputters and chugs significantly at over 3500 rpms and does some under load at lower rpms. Have looked around under the hood on the passengers side firewall for a fuel filter...


This model car has a "permanent" Fuel filter/pump combination. It is not meant to be changed. The filter/pump combo is in the fuel tank and can be accessed from under the back seat. I am highly doubtful that the filter is the malfunction you are experiencing. When your vehicle has low power and runs rough rough at low RPM's and then starts misfiring at 3500 RPM, it sounds like your timing belt has stripped some cogs and is in the process of shredding. THIS IS AN ENGINE EMERGENCY!!! IF THE BELT FAILS COMPLETELY AT HIGH RPM IT WILL DESTROY YOUR ENGINE!!! Do not fool around with changing sensors until you have had this checked out. If your DTC is saying that the MAP (Manifold Absolute Pressure) sensor or TDC (Top Dead Center) sensor is bad, check the timing belt.

4.3 liter engine, got bad gas, fuel pump went out, replaced it, in line filter has been replaced 3 times now and it still starts bad and idles rough, runs good at higher speeds though, just changed the...


Are you sure it's bad gas causing the problem? It could be a faulty idle sensor or more than likely the coolant sensor near the thermostat housing malfunctioning. It could be sending the wrong signal to the pcm(power control module) causing the timing to be too far advanced thus causing the low speed chugging & hard starting. Good luck!

1999 Mystique keeps missing (chugging) at higher


You should be illuminating the check engine light. If so, rent a scanner, read the codes and pursue to repairs. You should replace the fuel filter and check the air cleaner. The fuel pump may be on it's last legs--check fuel pressure at the fuel rail over the injectors (a tire-valve looking test port). The pressure should be ~45 to 55 PSI with the engine running.

Runs rough and dies at low rpms


This can be a number of things but you can try process of elimination.

It could be:
1. Bad spark plugs, wires or rotor
2. Fuel pump ,not getting enough fuel, check and replace fuel filter
3. Not getting enough air, check filter or clog
4. Try getting a fuel injection cleaning.

Without seeing it or hands on it could be a number of things.

try checking those to start to narrow it down. And it always could be something else as well such as timing etc..
