We need to find an inexpensive way to find the answer to our car problem. Sorry if our donation is small at this time - we are monetarily challenged at the moment. Stage IV cancer for wife and loss of job the same week for me. Here is our problem:

Recently replaced spark pugs and ignition wires. Car starts quickly... but then hesitates during acceleration. Gentle acceleration seems to work most times. When you step on the gas.. it just won't go! What should we consider next?

Thank you,
Nelson and Debbie
