I thoroughly cleaned the the egr port today and im still throwing the same codes...any suggestion?

 

I would hate to have you keep throwing parts at the car and wasting money.

Does this problem happen consistently when the car is under load? Do you have a volt meter?

 

Yes i do

 

If the car consistently does this, then you may want to test for voltage. The easiest way would probably be at the cigarette lighter with a volt meter. Have someone ride with you and see if the voltage drops when you accelerate.

The other way is to pick up one of those battery testers that you plug into your cigarette lighter.

 

Let me start from the beginning as far as the symptoms. It first threw the codes one night when i was driving one night on the highway going about 70mph. First thing i did was change the Bosch plugs and wires to ngk. Second i cleaned the egr valve thoroughly. Next, I read a post on here that said it was the distributor. ....not that. Last thing i did was clean the injectors and the fuelrail thoroughly. After all this, the car will start fine and idle fine cold, but as soon as it heats up,it starts to drive rough and want to turn off. Now with that being said, do you think its the alternator? Because on the highway at about 70mph the car rides fine.
Btw i appreciate any hrlp you can give me!

 

Just so things are less confusing, start a new thread. One thread with possibly two different problems is confusing.

 

I am throwing p0302 p1399 and have done a tune up cleaned egr ports and intake swapped injectors adjusted valves any other suggestions

 

I'm having the same issue.0300 0303 0304 and 1399. So, multiple AND random misfires. I recently had replaced my plugs, wires, dist cap and rotor...so I know it is not that. Could it possibly be the coil? Or would that cause misfiring on all 4 cylinders?

 

Look inside your distributor for any oil or red dust.

 

I would also check the crank timing and balance shaft pulleys to see if any debris could be blocking a signal from being read by the sensors.
