Please help. I was driving home from grocery shopping a week ago and my engine began shaking and had a loss of power. It only did this while at low RPM's. Like after going into 3rd gear at 30mphs for example, but it will do it in any gear. My check engine light came on 5-6 months ago. I got a OBD2 scanner and it said bad ignition coil and bad egr flow. I ended up raplacing the ignition coil #3, DPFE solinoid sensor and EGR solinoid, the EGR valve was working. The check engine light went off but problem was still there, so I replaced the following. The rest of the ignition coil boots with springs, pcv valve, spark plugs, oil filter, oil. I repaired all the vacume leaks, cleaned the MAF sensore with special cleaner. Im out of options. No codes show up anymore on my scanner and the problem is still there. I tried to explain it to a mechanic, but they still insist I spend the money for all the diagnostice to even get started. I have alread spent over $300 on this project and I just got layed off 3 weeks ago. Im in a bad spot and cant afford to start over at a mechanic. Could you throw some ideas at me, or give me some ideas of things I can check. I have googled a hundred different ways and only thing left I can think of are the cylinders themselves. PLEASE help. Thanks in advance. PS. Could a leaky EGR valve cause this problem?
have the same problem?
