I recently had a small car dealer power wash my engine and they didnt know what they were doing and put somekind of armoral and right after my car started acting like it was running out of gas and the check engine light was blinking and says there is a missfire. So they took my to there machanic and they said at first the #1 starkplug was the problem and they cleaned it then replaced it but still the problem accured and then they said it was the injector code was coming up so they needed to take the top of the motor off and clean the injectors so I dropped off the car and they didnt want to do it because it was going to cost to much and said the injector code wasent coming on now. Now im stuck with this problem. He said he blew in the upper part of the motor where the injectors are without takink it apart and it did run great for about 30 miles the when I slowed down it started again. He said to run the car for two weeks and come back but I think there pulling my leg and want me to go away. The thing is I dont want to run my car the way it is. My manual says not to drive it when the light it on. Im thinking I have to dry out under where my injectors are because that stuff they sprayed looks wet still and holds water. (Thick) can I do it myself is it a easy job to take off the cover where it says 3.4 and dry it myself or replace the injectors? And do you have a manual that tells me how to do this?

It sounds like you have moisture in the wiring connectors for the injectors or the ignition system. First, make sure none of the ignition coil towers are corroded. Pull the plug wires from the coils and visually inspect them. Next, unplug the electrical connectors from the module under the coils. Check for any moisture in the connectors. I would find my own mechanic to check the vehicle over, then have the car dealer pay the bill. I would also seek legal advise on the situation asap.

Thank you for your fast response! I did take off the ignition modual and test it. It had moisture in there and I sprayed it with some sort of coil electrical spray that the auto parts sold me. And everything was good and I put new wires and still the same. So my question is: to clean the electrical wiring to the injectors do I have to take apart the top of the motor where it says 3.4 and clean the wires thats plugged in the injectors. Or is it somewhere I can get to them by myself. + I have a 2002 dodge imtrepid 3.5 and I did the belts on them today and right after I was done the car started acting like it was going to die and I thought I over tightened them so I loosened them and still the same but I tried without no belts for less than a minute and still the same problem. Do you think this is a coincidence that maybe something else went wrong with my motor at the same time as when I replace my belts. The car was running fine last night. Only once in a while a sqealing soung would come from them. I also took one of the tension pulleys all the way off. I hope I didnt do anything that I wasent suppose to. The autoparts store said my cars pulley was spring loaded but my car isent I think thats the 2.7 I took it all apart and looked at it and I dont see any spring. Theres a long bolt that I have to tighted and loosen and thats hooked to the pulley wich has to be loosened and together they slide down to let the belt off. I called the autoparts store and they said I was probaby my fuel pump but im not to convinced because like I said it was working right befor I decided to change the belts. And I cleaned the negitive post on the battery also. If you can help me with this I would appreciate it. And I will not forget about you in the end thanks jokerstats.

Yes, remove the upper intake manifold to get to the injector connectors. Be sure to install new manifold gaskets.
