    I have a 99 Isuzu Rodeo with the 2.5L 4 cylinder in it, had an oil drainback problem, oil was building up in the valve cover, and getting sucked into the throttle body, sent it to the shop, fixxed, ran fine for about a week or two, and suddenly it developed a miss at idle and when you take off, or give it gas, if I take off easy in it, I mean very easy, it doesn't really miss at all but any time I give it any throttle at all it developes a very bad miss and won't pull for crap, once it gets to the speed I want to go the miss goes away, but if I give it just a hair more throttle it starts to struggle and miss, It is very bad, I have a hill on the way to my house and by the time I get to the top of it I am in 2nd gear if I take it very fast or 1st gear if I drive normal, Does any one have any idea of what could be causing this???????????:shrug:

    This isn't a ford prob, so I put it in talk. Thanks in advance if anyone has an idea.

    Yeah what he said, but, pull the codes (if there are any) and check your O2 sensors, they might be givin the ECM bad readings and causing it to run too rich.
