Sputtering and bucking

Is the Check Engine Light ON when the engine is running? Setting the IGNITION Timing on these vehicles could be a little tricky. I seem to remember you need to have the engine warmed up and " tell " the computer you wish to check IGNITION timing. This is done by using a jumper wire at the Diagnostic Connecter under the HOOD on the left side. Do you recall using a jumper wire at this connector?

No check engine light and I followed the instructions for setting the timing!

OK....If all those new ignition parts are still functioning correctly...then we usually start testing FUEL DELIVERY. I understand repairs have been done ...but.....new parts do fail occasionally. This system is usually tested by using a FUEL PRESSURE GAUGE. One could road test the vehicle while monitoring Fuel Pressure. If fuel delivery is at Specs....then we should go back and check the IGNITION SYSTEM. BTW...when was the THROTTLE BODY and IAC cleaned?

I used some cleaner on throttle body a couple days ago! Takes with my father in law and we are both in agreement that it's definitely a fuel issue, so I'm gonna save some money and pull the injectors and have them tested and cleaned

Sounds like a plan. Let us know the results.

Hi...did you ever find a repair for the problem you were having with this vehicle?

Vehicle fixed?

Finally got injectors cleaned and put back in and seems to be running worse! Has a miss at idle now and spits and sputters worse it seems. Not sure what to make of it

What method was used to "clean injectors" Sounds like we have to go back to square one. What is the FUEL PRESSURE at idle? What is FP under load? Quoting TC..." If the fuel pressure is not right ....nothing is right."

Sent them to shop for testing and cleaning

Well....IF....."timing was off".....consider checking the timing BELT/CHAIN.....may have jumped a tooth/link. What ENGINE is in this vehicle?

Hi Dustin. Did you ever resolve the issue with this vehicle?
