  6. Sputtering and misfire all of a sudden

    in Virtual Mechanic

    Posted

    So I let the car warm up for 20 mintues, drove it down the street 3 miles or so. Parked and let it run for 5 mins. Then got back in to drive back home and next thing I know getting into boost its starts to backfire and sputtering.

     

    I'm gonna run a check on the error codes when I get home today. Could the culprits be the Secondary injector, or FPR?

  10. Slight hesitation when driving

    So yesterday I finished up rebuilding the TB and wiring up new injector clips. Throttle response is way better with the new injector clips (old clips where on there last leg) .The hesitation is still there though. Its starts to hesitate once I get going and when I keep it at a constant roll... Any ideas? TPS?

     

    Thanks!

  14. Dump tube/wastegate dump madness

    I got a dump tube on my DSM, you will know when boost kicks in, all 30 psi of it, and when my anti-lag is turned on flames shoot out from underneath the car.... Its cool for a little while and there is a power gain from it but I like to hear just turbo spool. So it will be getting switched out with one that re-circulates. I can post pics of it when I get home.

    Heads crack often. There are non-jet valve replacement heads which seem to be fine.

     

    probably the most common problem I've ever heard of is the exhaust manifold either cracking and leaking or warping and breaking the rear studs on th head. If your manifold leaks at the back next to the head, you should take it off, cut between the runners and have it resurfaced. And get new studs, probably.

     

    ok cool. Thats the kind of answer I was looking for, I know that HG's, turbos, and all that other stuff are common items that wear out over time. Thanks technology!

    Whats up guys im Matt, I am a new enthisuast for the starquest community. I have built and destroyed many DSMs (still own one more currently), owned a few mustangs and just recently sold my SC'd S2K. Just bought an 88 starquest 147,00 miles (engine rebuilt at 92,000 miles) last Friday to have something to drive back and forth to work. I have found some minor issues with the car such as, a brown tarnish around the TB, the steering is super sloppy, and after a recent rainy day I found water on the driverside floor board (the car was parked all day that day). I have ordered all new injector seals and TB rebuild kit to solve the brown tarnish around the TB area. If you guys have an input on any of this or some other things I should inspect/replace that would be great. I have checked some of the newbee sticky's and searched some info, just looking for other ways to improve this car and get it running the way it should. Thanks fellas!!! :thumbsup:
