I'm getting a '97-98 S14 SR into my' 96. The prob is that the shop is having a slight problem with the hestiation probs. He says it idles and runs fine, but around 4-5k rpms it feels like fuel cut. He checked the wiring and grounding 3x, maf, plugs and ecu and could not find any wrong. I heard this was a common prob. I've searched, but all fingers point to the above that were checked. Any suggestions?

Thanks.

 

re-check the timing

 

Ok I finally had time to check out my car.

Symptoms: Car runs real rich and acts like it's running on 1 less cylinder. He said at 4-5k rpm it cuts like fuel cut,

MAF was switched w/ an S13 SR, got new plugs, swapped coil packs, swapped another ECU, wiring was checked 3x, timing checked. The harness was hand delivered to McKinney yesterday...Anyone?

 

..and it's not the IC/piping.. it s brand new RSPL

 

Have you changed out your injectors, fuel pump. Maybe you have a dirty injector?
