Very poor running wrx...
('95 WRX w/polar performance product 1 chip)
I filled up the car yesterday with superunleaded. when i was coming out of the station I noticed that the engine was vibrating more, like the flat 4 'wobble' from side to side... enough to feel inside the car and rock the suspension slightly I fitted (4) new coil packs yesterday afternoon and since I have virtually no boost, boost gauge is showing boost (reading from manifold about 13psi, chip mapped to 16.11psi - not sure whether this is manifold or turbo outlet rating...) but the car isn't pulling at all... it feels like a N/A engine, right through the rev range - feels like no boost. It feels very lumpy, sluggish, and slow revving The fuel economy is far worse... normally get 100km to 1/4 tank, got 36km to 1/4 since yesterday :confused: Have tried resetting the ECU to no avail... Don't think there are any air leaks round the IC pipework etc... Any other things I should be checking? I put the coil packs in as the old ones were cracked and missfiring, but with the car performing poorly after coming out of the garage I don't know if it is a knock on effect from it? |
Things I'm going to check tonight:
Take the VTA DV off Clean boost solenoid Check injector connections check fuel filter check oil filler for smoke check T.P.S clean MAF best case scenario some connectors/sensors are loose... worst case melted piston? what are the symptoms of a melted piston? |
Wastegate Actuator Maybe?? I had the same problem! 2min Job and it was fixed...

?????????????
why did you change the coil packs?? are you sure they are 100%, to me sounds like she is miss firing, that would give you a wobble, check all wiring to sensors and vacum pipes in case ya knocked something off, wud not think its ur fuel, not only after just filling it, unless u were empty
|
I changed the coil packs due to it missfiring after upping boost with the polar chip. The old coil packs were cracked at the tips. I was nearly empty - took 46 litres to fill it to the neck.
Thing is it started to wobble before I changed the coil packs...? Would the wastegate actuator result in these symptoms? I'll try tightening it, clockwise to tighten right? |
I dont know about the wobble, but I lost pretty much all boost, and my dump valve and induction kit were useless.....NOTHING! Revs were slow and it felt like a N/A car.... Exactly the same as what you were saying!
And it was all down to the waste gate actuator comming loose! Its worth a try! |
Have you checked your plugs ?

Sorted - one of the coil packs I bought had a loose connection inside the connector head :rolleyes: was running on 3 half the time but going well now :thumb:
