Chances are you had a random misfire until you replaced the plugs. I would check the converter and make sure the fuel pressure is where it needs to be.

Let me know what you find.

Today while driving the car, it started making a high pitched noise, so we pulled over and stopped. After that the car would not accelerate. Now it won't go into any of the gears. Any ideas re: the problem?

If I had to guess, I would say the front pump went bad on the trans.

Hi Chasity,

The power steering pump and not going over 30 MPH don't really have anything to do with each other so I suspect you have two issues. Did this 30 MPH issue start immediately after changing the pump or a little while later?

Either way, we need to find out what codes are in the system. I suspect the vehicle is in what is called limp mode which is a protection mode so that nothing is damaged when the ECM sees something wrong it puts into this mode but it will also set some codes so we can figure it out.

Let me know this info and we can go from there. Thanks

After I replaced to power steering pump. The codes are PO155, PO1401, PO1506, PO174 and PO175. I installed an ERG sensor. And EGRvalve. Replaced the radiator to. When I parked the car it ran fine. The only thing I did was put gasket on, replaced radiator and power steering pump.

Great information. Yes. Based on those codes you had a lean condition and clogged converter is one of them. However just make sure you keep an eye on fluid levels because the main cause of plugged converters is coolant or oil going through the engine.

Thanks for following up.

It got into a wreck almost two years ago so it's been sitting in my yard since. I
recently have been driving it for the past week. I noticed when I first drove it a really bad gas smell. Then I started noticing it trying to jerk while going into gear on the highway. My foot would get warm through my shoe while accelerating. Two days ago I stopped driving it because it got to where it won't go past 20 mph or go past first gear. I checked the diagnostics and one code popped up for p1633. I have put on a new camshaft sensor, new fuel line, and new fuel filter. Could anyone tell me what could be wrong with my car?
