I have a 99 ranger with the 2.5 liter in it. It has rough idle and loss of acceleration power. It is not throwing the check engine light and obd2 scanner shows no codes. Shop claim they did a compression test and cylinder 2 and 3 has zero compression. That dont sound right to me as i feel it would certainly illuminate the cel and show dtc for misfire. Plugs wires and air intake temp sensor all replaced. What do you guys think.
