This morning I was on my way to work and everything was going fine. Waited for the car to warm up, did my daily redline, everything felt great. I pulled into a parking lot near my building for work and stopped. when I stopped, the car just shut off. When I cranked it back up it started and then I had 0 throttle response and the car died again. Tried a few more times and had the same problems.

so I pushed it into a parking spot and started searching the forum. Tried unflooding, but the unflooding thread I read didn't mention holding the gas pedal down (found out after I got into my office). After trying I had the same issue. So I left it parked and went to work.

From what I read, it seems like it's either the fuel pump, ignition coils, or compression.

I just replaced the spark plugs and changed oil on Sunday. Drove the car yesterday with 0 issues. Spark plugs actually helped quite a bit with some stuttering when starting off in first. Coils were replaces about 10k ago, so they were going to be the next replacement, but I don't drive it often and upgrade kits are expensive so I wasn't going to do it this soon.

Compression test was done about 10 months ago with great numbers on all sides. Don't remember the exact results unfortunately. I've driven about 4k miles since then.

I'm running a BHR catless midpipe.

Haven't had a chance to check if I have a new engine code because I didn't have my ultragauge with me this morning, but I always have an engine light because of the midpipe, so I can't say I have anything new off the engine light.

Just wanted to get some insight or priority of things to check since I'll be in a parking lot and it's going to be like 110 out today. Trying to avoid paying for towing if possible.

Thanks

 

I was able to run a code on it. P0301. Local rotary shop suggested coils. I'm guessing coils. I cranked it and it started but it wasn't happy about it. Didn't let it run long, so probably flooded it. Going to try and go get some coils today if possible. Swap them in the parking lot and hopefully drive it home.

 

It's recommended to change plugs/coils and wires at the same time, as the death of one leads to the death of the other (which kills the cat, which kills the engine)
However, the cheapest method is to invest in a coil tester so you can perform your own troubleshooting.

 

Pulled the ignition stuff apart and it turned out one of my plug wires had corroded and broken under the end cap. Ended up replacing them and the coil packs since the coil packs looked pretty haggard too and now everything is great.

Just thought I'd leave an update in case anyone else comes across this and has weird similar symptoms to what I had.

 

Good advice. I was under the understanding that before buying the car, the previous owner changed them somewhat recently, but I guess I should have pulled it apart and checked anyways. Had plans to upgrade soon, which is why I went with just plugs, but I'll be putting off the upgrade for a little while now.

Thanks to Advanced Auto having an online coupon, my coilpacks were only like $110 for all 4. Intermotor brand. On here I found at least one person who said they were an OK replacement outside of OEMs. Went with NGK plug wires.

 

Looks like you did the proper inspections and replacements. Good work. When these coils run their course then you can upgrade to the BHR coils and wires.
