Re: wats do i do
Is it just me or was that a little hard to read?
I would check you codes first to see what sensor/s might be bad. If your SES light stays on there is something not working right. Here is the tech article on how to do that--> LINK.

Check your codes first with grimmcs link. No offense but please type with some grammar, its alot easier for people to read any future questions.

i think its my fuel injectors?
whenever i turn on my car now it shakes and rumbles and im scared to stop while driving for it may turn off. The rpm meter goes to about 2 when i put the car in park and the car wants to go forward. When in drive and at a complete stop it stays at 1 rpm and really wants to move forward. when parked and the meter says rpm 2 It sounds as if im pushing the gas. And ive noticed that sometimes the pedal for the acceleration seems easier to push in at times and hard at others. What could this be because i really love my car and i dont want to sell it?

Re: i think its my fuel injectors?
Like I said in your other thread, about the same problem, check your codes and get back to us. It sounds as though one of your sensors has or is going bad. It might be the IAC. I wouldnt even think about selling.

Re: wats do i do
The first thing I suggest is to type clearly. It's hard enough to try and diagnose a problem over the internet with nothing but a description, but when people have to try to decipher what your writing, 90% will go onto the next post. If you want proof, look at your view to reply ratio..including this post you have 4 replies and 71 views, that means 67 people just moved on.
As for the car, check the codes stored in the ECM and let us know what they are. When your check engine light comes on, the ECM has detected a problem with the engine controls and is trying to let you know something is wrong. Pull the code and we can try to get you going down the right track.

It could even just be your TB plate getting stuck too far closed and getting stuck out ie. the low and high RPMs - that can even trip a code sometimes.
There are a ton of simple things it could be, go over the basics first.
IAC - clean it or get a new one.
If your car has a MAF - clean it or get a new one.
Check all your vaccuum lines. And check them again. And again.
Check your EGR valve - maybe yours is electric, if it is, I don't know how you'll do that, but if it isn't, its easy to check.
TPS - adjust it or get a new one and adjust that one, too.
All of the above things can lead you to a funky idle. Pick up a Hayne's manual if you don't allready have one - they make life much easier.

Re: i think its my fuel injectors?
If I had to guess, I would say english is his second language, at least he's trying. As far as your problem, sounds like a throttle position sensor to me, had the same problem with my Jeep. I cleaned the contacts on the tps on the Jeep and that fixed the problem for me.

Re: i think its my fuel injectors?
I would think that is a "reminder" buzzer. I disconnected mine, but it lets you know that the lights are on, seatbelt is not fastened, and keys in ignition when the motor is off and, IIRC when the door is open. I don't have a working seatbelt warning light in the dash (Dakota Digital) and the seatbelt warning won't stop.

Re: i think its my fuel injectors?
You can order new injectors, get ones from a JY for cheap, or get the ones you have right now rebuilt which shouldn't cost that much. Have you removed the injectors before?

Re: i think its my fuel injectors?
Did anybody else catch the part about a flashing check engine light?
A flashing check engine light indicates that the computer has failed internal diagnostics on the integrity of its programming. The car then runs in complete limp home mode bypassing the PROM.
This is usually due to a loose memcal or a bad ECM.

Re: i think its my fuel injectors?
Just to be clear.. The check engine light is flashing while the car is running?
The memcal is a small board that contains the PROM for the car. The PROM is a chip that stores the code to run your car. If you look at the ecm, it will have a small cover on it. You can remove this cover and visually inspect the memcal.

Re: i think its my fuel injectors?
The memcal is removable... It is in a socket. Sometimes it gets loose.
The ecm is a silver box under the passanger side kickpanel. Remove it... YOu need a 7mm socket. It will drop down. Remove the cover, and look at the memcal. You might even try removing it and reseating it.
