    So i found a 1995 sr5 for sale. The guy I got it from rebuilt the motor. He had the heads rebuilt by a very reputable machinist where I'm from. He did not do it cheap at all. The only thing is it seems like he missed something. It acts like the timing is off. So I checked and sure enough both cams were off by a tooth. I got that set right and put a timing light to it. That helped a little but it's still not running right at idle it sounds fine but under a load it seem like it is missing. Loss of power really bad. Has a really bad raw fuel smell in the exhaust. I'm not sure where to go with it at this point. Any help would be greatly appreciated.

    Did you mess with your distributor at all?

    We set the timing using it. New plugs and wires also.

    Did you double check plug gaps?

    How old is the timing belt?

    Plugs are gapped right. Timing belt has very little miles on it. The guy I bought it from said 350 miles on it. You can still read the part numbers on it.

    Hmmm.......well if you think you've got the timing issues figured out. Only other thing there I could think of is a bad or loose pully.

    Any old bad gas in that thing from sitting around a long time? Maybe some heet if there's any water in there. Fuel pump, fuel filter, fuel injectors.....for the hell of it go check all the connections on the injectors. Make sure nothing is loose.

    We are headed to the crank pulley next. The guy that rebuilt it made some pretty stupid mistakes so we are checking all that also. He put new connectors on the fuel injectors so maybe he mixed 2 of then up.

    Have you inspected the heads yourself or done a compression check? Not to question the work done by the machine shop you trust, but how he sealed it.

    Have you checked that the TPS is adjusted correctly?

    I have checked compression it's good. I have not taken the heads off I was hoping to not have to got that far tell i knew everything else was good. I have never checked the tps it's new I'm not sure why it would need adjusting.

    I've had to adjust a new one before on my pickup only reason I brought it up. Had kind of the same symptoms. It idled well but would miss/fall on its face under throttle. The ECU uses TPS values to determine timing for the EFI. Could be out of whack causing the miss. Just an idea. Also vacuum leaks or miss routed lines I've had similar symptoms to yours with leaks as well.
