Okay guys, just a recap, I got this 87 TurboII about 2 months ago. Has been running good besides hot start issues. I was told it was recently rebuilt when I bought it, and apparently has a streetport. All deletes have been done as well.

So today I noticed what sounded and felt like a misfire. Drove pretty normal but sounded off. Idle is now rough. Pulled the plugs and did a poor mans compression test, front rotor sounds healthy and even, rear had a slight uneven pulsing. One strong pulse then two less strong ones. But it wasn't a huge difference. I also discovered the last owner had the plugs in wrong. So I had some new NGKs and I put them in, trailing up top and leading on the bottom. Started it but no change-idle still bad. Drives normalish- but sounds off and broke up in 2nd at high Rpms.

I've also always had hot start issues and lately it seems my cold starts have gotten a little worse. I admit it seems like it may be an apex seal but I wanted to ask first. Figured it could also be a coil pack. Some possibly unrelated info: intake filter smells like fuel? Not coming from the mani, actually smells from the filter. Also, when I brought his car home it's fan stopped working and she got relatively warm, never seemed to cause an issue though once I got a good fan in. Figured I'd mention it.

So, is it safe to assume she's on her way out?

 

welcome to the board.

it might be a good idea to do an actual compression test and get some numbers to work with.

that said, is the fuel system modified or is it stock? when was the last filter change?
