>you usually have to tilt the engine forward to get to the ones in the back
I have a feeling that this means loosening engine mounts or something like that and then re-tightening them. This might be beyond the limits of my tools-on-hand, physical strength and courage.
 
>the other would be to check the resistance of the injector with a multimeter
Now that sounds like its a bit less arduous a task. Does one do this while the engine is running? How do I get the fuel injector naked so it can be tested?

misfire problem by millwright91

I have a 98 venture that has developed a bad misfire. I scanned it and all 6 are misfiring at different times. You can be driving and try to hold a speed and it goes to misfiring. Speed up quick and the misfiring goes away. Tested ignition mod. and orielly says it is ok.

Plugs and wires have about 25000 miles. Changed after we rebuilt the motor. We used ac delco wires and platinum plugs. The van has run fine for the whole time and all of a sudden it goes to miss firing. I changed the coils, cam sensor, crank sensor, and had the ignition module tested.

ok my husband wrote on here before about misfiring and codes.. he checked all the spark plugs got the transnmission cleaner stuff.. and its still misfiring.,.. my friend cleared the code for me and it came up with a 742 code... does anyone know what that is?
it seems to misfire off and on every few weeks runs like its gonna die when you are going between 0-55 mph... once you get above that it stops but the service engine light soon is still on..... any ideas would be great! i love my van just need it to run right?

Well, I tried to find a more specific thread in which to respond to this question, but couldn't so I'll respond to it here and then perhaps if there is any further discussion someone can find a more relevant thread where this problem can be discussed and perhaps already has been discussed:
 
Possibilities: Failure of the Torque Converter Clutch (TCC) Solenoid, the 2-3 Shift Solenoid and the Transmission Valve Body. If its the TCC solenoid then it will be 85.00 for parts and probably 300.00 for labor. Transmission Valve Body would be a bit less for parts but a good bit more in labor.
Good luck to you.

Is your check engine light on? If so, get the codes read and post...
